Fusion provides a couple of adapters for other sequences such as < tt class = "computeroutput" > < span class = "identifier" > std< / span > < span class = "special" > ::< / span > < span class = "identifier" > pair< / span > < / tt > ,
< a href = "http://www.boost.org/libs/mpl/index.html" target = "_top" > MPL< / a > sequences,
and < tt class = "computeroutput" > < span class = "identifier" > boost< / span > < span class = "special" > ::< / span > < span class = "identifier" > array< / span > < / tt > . These adapters are written using Fusion's
non-intrusive < a href = "extension.html" title = "Extension" > Extension< / a > mechanism.
If you wish to use these sequences with fusion, simply include the necessary
2008-07-21 07:25:52 +00:00
files and they will be regarded as first-class, fully conforming fusion sequences.

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 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 >
sequences, include:
< / p >
< pre class = "programlisting" >
< span class = "preprocessor" > #include< / span > < span class = "special" > < < / span > < span class = "identifier" > boost< / span > < span class = "special" > /< / span > < span class = "identifier" > fusion< / span > < span class = "special" > /< / span > < span class = "identifier" > mpl< / span > < span class = "special" > .< / span > < span class = "identifier" > hpp< / span > < span class = "special" > > < / span >
< / pre >
< 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:
< / p >
< pre class = "programlisting" >
< span class = "preprocessor" > #include< / span > < span class = "special" > < < / span > < span class = "identifier" > boost< / span > < span class = "special" > /< / span > < span class = "identifier" > fusion< / span > < span class = "special" > /< / span > < span class = "identifier" > include< / span > < span class = "special" > /< / span > < span class = "identifier" > mpl< / span > < span class = "special" > .< / span > < span class = "identifier" > hpp< / span > < span class = "special" > > < / span >
< / pre >
< p >
The header includes all the necessary headers.
