Fusion provides a couple of adapters for other sequences such as arrays, <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">pair</span></code>,
<a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a> sequences,
and <code class="computeroutput"><span class="identifier">boost</span><span class="special">::</span><span class="identifier">array</span></code>. These adapters are written using Fusion's
non-intrusive <a class="link" href="extension.html" title="Extension">Extension</a> mechanism.
If you wish to use these sequences with fusion, simply include the necessary
files and they will be regarded as first-class, fully conforming fusion sequences.
</p>
<p>
Fusion also provides various schemes to make it easy for the user to adapt
various data structures, non-intrusively, as full fledged Fusion sequences.

Fusion sequences may also be adapted as fully conforming <a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>
sequences (see <a class="link" href="sequence/intrinsic.html" title="Intrinsic">Intrinsics</a>).
That way, we can have 2-way adaptation to and from <a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>
and Fusion. To make Fusion sequences fully conforming <a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>

<p>
If you want bi-directional adaptation to and from <a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>
and Fusion, simply include:

The above macro generates the necessary code to adapt <code class="computeroutput"><span class="identifier">type_name</span></code>
as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random
Access Sequence</a>. The sequence of <code class="literal">(attribute_type<span class="emphasis"><em>N</em></span>,
attribute_const_type<span class="emphasis"><em>N</em></span>, get_expr<span class="emphasis"><em>N</em></span>,
set_expr<span class="emphasis"><em>N</em></span>)</code> quadruples declares the types,
const types, get-expressions and set-expressions of the elements that are
part of the adapted fusion sequence. <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code>
is the expression that is invoked to get the <span class="emphasis"><em>N</em></span>th element
of an instance of <code class="computeroutput"><span class="identifier">type_name</span></code>.
This expression may access a variable named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>
or <code class="computeroutput"><span class="identifier">type_name</span> <span class="keyword">const</span><span class="special">&amp;</span></code> which represents the underlying instance
of <code class="computeroutput"><span class="identifier">type_name</span></code>. <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code>
and <code class="literal">attribute_const_type<span class="emphasis"><em>N</em></span></code> may specify
the types that <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> denotes
to. <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to set the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access variables named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>,
which represent the corresponding instance of <code class="computeroutput"><span class="identifier">type_name</span></code>,
and <code class="computeroutput"><span class="identifier">val</span></code> of an arbitrary const-qualified
reference template type parameter <code class="computeroutput"><span class="identifier">Val</span></code>,
which represents the right operand of the assignment expression.
</p>
<p>
The actual return type of fusion's intrinsic sequence access (meta-)functions
when in invoked with (an instance of) <code class="computeroutput"><span class="identifier">type_name</span></code>
is a proxy type. This type is implicitly convertible to the attribute type
via <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> and forwards assignment
to the underlying element via <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code>.
The value type (that is the type returned by <a class="link" href="../iterator/metafunctions/value_of.html" title="value_of"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at.html" title="value_at"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at</span></code></a> and <a class="link" href="../sequence/intrinsic/metafunctions/value_at_c.html" title="value_at_c"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_c</span></code></a>) of the <span class="emphasis"><em>N</em></span>th
element is <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code> with const-qualifier
and reference removed.
</p>
<p>
The macro should be used at global scope, and <code class="computeroutput"><span class="identifier">type_name</span></code>
should be the fully namespace qualified name of the class type to be adapted.

<p>
The above macro generates the necessary code to adapt <code class="computeroutput"><span class="identifier">type_name</span></code>
as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random
Access Sequence</a> and <a class="link" href="../sequence/concepts/associative_sequence.html" title="Associative Sequence">Associative
Sequence</a>. The sequence of <code class="literal">(attribute_type<span class="emphasis"><em>N</em></span>,
attribute_const_type<span class="emphasis"><em>N</em></span>, get_expr<span class="emphasis"><em>N</em></span>,
set_expr<span class="emphasis"><em>N</em></span>, key_type<span class="emphasis"><em>N</em></span>)</code>
5-tuples declares the types, const types, get-expressions, set-expressions
and key types of the elements that are part of the adapted fusion sequence.
<code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to get the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access a variable named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>
or <code class="computeroutput"><span class="identifier">type_name</span> <span class="keyword">const</span><span class="special">&amp;</span></code> which represents the underlying instance
of <code class="computeroutput"><span class="identifier">type_name</span></code>. <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code>
and <code class="literal">attribute_const_type<span class="emphasis"><em>N</em></span></code> may specify
the types that <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> denotes
to. <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to set the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access variables named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>,
which represent the corresponding instance of <code class="computeroutput"><span class="identifier">type_name</span></code>,
and <code class="computeroutput"><span class="identifier">val</span></code> of an arbitrary const-qualified
reference template type parameter <code class="computeroutput"><span class="identifier">Val</span></code>,
which represents the right operand of the assignment expression.
</p>
<p>
The actual return type of fusion's intrinsic sequence access (meta-)functions
when in invoked with (an instance of) <code class="computeroutput"><span class="identifier">type_name</span></code>
is a proxy type. This type is implicitly convertible to the attribute type
via <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> and forwards assignment
to the underlying element via <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code>.
The value type (that is the type returned by <a class="link" href="../iterator/metafunctions/value_of.html" title="value_of"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of</span></code></a>, <a class="link" href="../iterator/metafunctions/value_of_data.html" title="value_of_data"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of_data</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at.html" title="value_at"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at_c.html" title="value_at_c"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_c</span></code></a> and <a class="link" href="../sequence/intrinsic/metafunctions/value_at_key.html" title="value_at_key"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_key</span></code></a>) of the <span class="emphasis"><em>N</em></span>th
element is <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code> with const-qualifier
and reference removed.
</p>
<p>
The macro should be used at global scope, and <code class="computeroutput"><span class="identifier">type_name</span></code>
should be the fully namespace qualified name of the class type to be adapted.

<p>
The macros should be used at global scope, and <code class="computeroutput"><span class="identifier">struct_name</span></code>

<p>
The above macro generates the necessary code to adapt <code class="computeroutput"><span class="identifier">type_name</span></code>
or an arbitrary specialization of <code class="computeroutput"><span class="identifier">type_name</span></code>
as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random
Access Sequence</a> and <a class="link" href="../sequence/concepts/associative_sequence.html" title="Associative Sequence">Associative
Sequence</a>. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">template_param0</span><span class="special">)(</span><span class="identifier">template_param1</span><span class="special">)...</span></code>
declares the names of the template type parameters used. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">specialization_param0</span><span class="special">)(</span><span class="identifier">specialization_param1</span><span class="special">)...</span></code> declares the template parameters of the
actual specialization of <code class="computeroutput"><span class="identifier">type_name</span></code>
that is adapted as a fusion sequence. The sequence of <code class="literal">(attribute_type<span class="emphasis"><em>N</em></span>,
attribute_const_type<span class="emphasis"><em>N</em></span>, get_expr<span class="emphasis"><em>N</em></span>,
set_expr<span class="emphasis"><em>N</em></span>, key_type<span class="emphasis"><em>N</em></span>)</code>
5-tuples declares the types, const types, get-expressions, set-expressions
and key types of the elements that are part of the adapted fusion sequence.
<code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to get the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access a variable named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>
or <code class="computeroutput"><span class="identifier">type_name</span> <span class="keyword">const</span><span class="special">&amp;</span></code> which represents the underlying instance
of <code class="computeroutput"><span class="identifier">type_name</span></code>. <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code>
and <code class="literal">attribute_const_type<span class="emphasis"><em>N</em></span></code> may specify
the types that <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> denotes
to. <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to set the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access variables named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>,
which represent the corresponding instance of <code class="computeroutput"><span class="identifier">type_name</span></code>,
and <code class="computeroutput"><span class="identifier">val</span></code> of an arbitrary const-qualified
reference template type parameter <code class="computeroutput"><span class="identifier">Val</span></code>,
which represents the right operand of the assignment expression.
</p>
<p>
The actual return type of fusion's intrinsic sequence access (meta-)functions
when in invoked with (an instance of) <code class="computeroutput"><span class="identifier">type_name</span></code>
is a proxy type. This type is implicitly convertible to the attribute type
via <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> and forwards assignment
to the underlying element via <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code>.
The value type (that is the type returned by <a class="link" href="../iterator/metafunctions/value_of.html" title="value_of"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of</span></code></a>, <a class="link" href="../iterator/metafunctions/value_of_data.html" title="value_of_data"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of_data</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at.html" title="value_at"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at_c.html" title="value_at_c"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_c</span></code></a> and <a class="link" href="../sequence/intrinsic/metafunctions/value_at_key.html" title="value_at_key"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_key</span></code></a>) of the <span class="emphasis"><em>N</em></span>th
element is <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code> with const-qualifier
and reference removed.
</p>
<p>
The macro should be used at global scope, and <code class="computeroutput"><span class="identifier">type_name</span></code>
should be the fully namespace qualified name of the template class type to
be adapted.

</h5>
<p>
The above macro generates the necessary code to adapt <code class="computeroutput"><span class="identifier">type_name</span></code>
or an arbitrary specialization of <code class="computeroutput"><span class="identifier">type_name</span></code>
as a model of <a class="link" href="../sequence/concepts/random_access_sequence.html" title="Random Access Sequence">Random
Access Sequence</a>. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">template_param0</span><span class="special">)(</span><span class="identifier">template_param1</span><span class="special">)...</span></code>
declares the names of the template type parameters used. The sequence <code class="computeroutput"><span class="special">(</span><span class="identifier">specialization_param0</span><span class="special">)(</span><span class="identifier">specialization_param1</span><span class="special">)...</span></code> declares the template parameters of the
actual specialization of <code class="computeroutput"><span class="identifier">type_name</span></code>
that is adapted as a fusion sequence. The sequence of <code class="literal">(attribute_type<span class="emphasis"><em>N</em></span>,
attribute_const_type<span class="emphasis"><em>N</em></span>, get_expr<span class="emphasis"><em>N</em></span>,
set_expr<span class="emphasis"><em>N</em></span>)</code> quadruples declares the types,
const types, get-expressions and set-expressions of the elements that are
part of the adapted fusion sequence. <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code>
is the expression that is invoked to get the <span class="emphasis"><em>N</em></span>th element
of an instance of <code class="computeroutput"><span class="identifier">type_name</span></code>.
This expression may access a variable named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>
or <code class="computeroutput"><span class="identifier">type_name</span> <span class="keyword">const</span><span class="special">&amp;</span></code> which represents the underlying instance
of <code class="computeroutput"><span class="identifier">type_name</span></code>. <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code>
and <code class="literal">attribute_const_type<span class="emphasis"><em>N</em></span></code> may specify
the types that <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> denotes
to. <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code> is the expression that
is invoked to set the <span class="emphasis"><em>N</em></span>th element of an instance of
<code class="computeroutput"><span class="identifier">type_name</span></code>. This expression
may access variables named <code class="computeroutput"><span class="identifier">obj</span></code>
of type <code class="computeroutput"><span class="identifier">type_name</span><span class="special">&amp;</span></code>,
which represent the corresponding instance of <code class="computeroutput"><span class="identifier">type_name</span></code>,
and <code class="computeroutput"><span class="identifier">val</span></code> of an arbitrary const-qualified
reference template type parameter <code class="computeroutput"><span class="identifier">Val</span></code>,
which represents the right operand of the assignment expression.
</p>
<p>
The actual return type of fusion's intrinsic sequence access (meta-)functions
when in invoked with (an instance of) <code class="computeroutput"><span class="identifier">type_name</span></code>
is a proxy type. This type is implicitly convertible to the attribute type
via <code class="literal">get_expr<span class="emphasis"><em>N</em></span></code> and forwards assignment
to the underlying element via <code class="literal">set_expr<span class="emphasis"><em>N</em></span></code>.
The value type (that is the type returned by <a class="link" href="../iterator/metafunctions/value_of.html" title="value_of"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_of</span></code></a>, <a class="link" href="../sequence/intrinsic/metafunctions/value_at.html" title="value_at"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at</span></code></a> and <a class="link" href="../sequence/intrinsic/metafunctions/value_at_c.html" title="value_at_c"><code class="computeroutput"><span class="identifier">result_of</span><span class="special">::</span><span class="identifier">value_at_c</span></code></a>) of the <span class="emphasis"><em>N</em></span>th
element is <code class="literal">attribute_type<span class="emphasis"><em>N</em></span></code> with const-qualifier
and reference removed.
</p>
<p>
The macro should be used at global scope, and <code class="computeroutput"><span class="identifier">type_name</span></code>
should be the fully namespace qualified name of the template class type to
be adapted.

<a class="link" href="algorithm.html#fusion.algorithm.lazy_evaluation">Lazy Evaluation</a>
</h4>
<p>
Unlike <a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>, Fusion
algorithms are lazy and non sequence-type preserving. What does that mean?
It means that when you operate on a sequence through a Fusion algorithm that
returns a sequence, the sequence returned may not be of the same class as the
original. This is by design. Runtime efficiency is given a high priority. Like
<a href="http://www.boost.org/libs/mpl/index.html" target="_top">MPL</a>, and unlike
<a href="http://en.wikipedia.org/wiki/Standard_Template_Library" target="_top">STL</a>,
fusion algorithms are functional in nature such that algorithms are non mutating
(no side effects). However, due to the high cost of returning full sequences
such as vectors and lists, <span class="emphasis"><em>Views</em></span> are returned from Fusion
algorithms instead. For example, the <a class="link" href="algorithm/transformation/functions/transform.html" title="transform"><code class="computeroutput"><span class="identifier">transform</span></code></a> algorithm does not actually
return a transformed version of the original sequence. <a class="link" href="algorithm/transformation/functions/transform.html" title="transform"><code class="computeroutput"><span class="identifier">transform</span></code></a> returns a <a class="link" href="view/transform_view.html" title="transform_view"><code class="computeroutput"><span class="identifier">transform_view</span></code></a>. This view holds a
reference to the original sequence plus the transform function. Iteration over
the <a class="link" href="view/transform_view.html" title="transform_view"><code class="computeroutput"><span class="identifier">transform_view</span></code></a>
will apply the transform function over the sequence elements on demand. This
<span class="emphasis"><em>lazy</em></span> evaluation scheme allows us to chain as many algorithms
as we want without incurring a high runtime penalty.

return <a class="link" href="view.html" title="View">Views</a> also allows operations such
as <a class="link" href="algorithm/transformation/functions/push_back.html" title="push_back"><code class="computeroutput"><span class="identifier">push_back</span></code></a> to be totally generic. In
Fusion, <a class="link" href="algorithm/transformation/functions/push_back.html" title="push_back"><code class="computeroutput"><span class="identifier">push_back</span></code></a> is actually a generic algorithm
that works on all sequences. Given an input sequence <code class="computeroutput"><span class="identifier">s</span></code>
and a value <code class="computeroutput"><span class="identifier">x</span></code>, Fusion's <a class="link" href="algorithm/transformation/functions/push_back.html" title="push_back"><code class="computeroutput"><span class="identifier">push_back</span></code></a> algorithm simply returns
a <a class="link" href="view/joint_view.html" title="joint_view"><code class="computeroutput"><span class="identifier">joint_view</span></code></a>:
a view that holds a reference to the original sequence <code class="computeroutput"><span class="identifier">s</span></code>
and the value <code class="computeroutput"><span class="identifier">x</span></code>. Functions
that were once sequence specific and need to be implemented N times over N
different sequences are now implemented only once. That is to say that Fusion
sequences are cheaply extensible. To regain the original sequence, <a class="link" href="container/conversion/functions.html" title="Functions">Conversion</a>
functions are provided. You may use one of the <a class="link" href="container/conversion/functions.html" title="Functions">Conversion</a>
functions to convert back to the original sequence type.
