|
|
<p>
|
|
<pre>
|
|
template<
|
|
typename Sequence
|
|
, typename T
|
|
>
|
|
struct remove
|

{
|

typedef <em>unspecified</em> type;
|

};

</pre>

<p>

|
<h3>Description</h3>
|
|
<p>
|
|
Returns a new sequence which contains all the elements from <code>[begin<Sequence>::type, end<Sequence>::type)</code> range except those that are identical to <code>T</code>. The result sequence preserves all the functional and performance characteristics of the original <code>Sequence</code>, except its size and identity.

<h3>Parameters</h3>
|
|
<table border="1">
|
|
<tr><th> Parameter </th><th> Requirement </th><th> Description </th></tr>
|
|
<tr><td><code>Sequence</code></td><td>A model of <a href="../Extensible_Sequence.html">Extensible Sequence</a></td><td>The original sequence. </td></tr>
|
|
<tr><td><code>T</code></td><td>A type</td><td>A type to be removed. </td></tr>

<h3>Expression semantics</h3>

|
<p>
|
|
<table border="1">
|
|
<tr><th> Expression </th><th> Expression type </th><th> Precondition </th><th> Semantics </th><th> Postcondition </th></tr>
|
|
<tr><td><code>typedef remove<Sequence,T>::type s;</code></td><td>A model of <a href="../Extensible_Sequence.html">Extensible Sequence</a></td><td></td><td>Equivalent to <code>typedef remove_if< Sequence,is_same<_,T> >::type t;</code>.</td><td></td></tr>

|
<h3>Complexity</h3>
|
|
<p>
|
|
Linear. Performs exactly <code><a href="../Reference/size.html">size</a><Sequence>::type::value</code> comparisons for equality.
|
|
<p>
|
|
<h3>Example</h3>
|
|
<p>
|
|
<pre>
|
|
typedef <a href="../Reference/list.html">list</a><int,float,char,float,float,double>::type types;
|
|
typedef remove< types,float >::type result;
|
|
typedef <a href="../Reference/list.html">list</a><int,char,double>::type answer;
|
|
BOOST_STATIC_ASSERT((<a href="../Reference/equal.html">equal</a>< result,answer >::type::value));
|
|
</pre>
