<h4>Description</h4>
|
|
<p>The templated class <code>map_std<I, T, ALLOC></code> provides a
|
|
wrapper for the standard library associative container
|
|
<code>std::map</code>. The wrapper has one simple purpose. It
|
|
allows the definition of a default template parameter (for the
|
|
adapted array) when declaring the sparse container types.</p>
|
|
<h4>Example</h4>
|
|
<pre>
|
|
#include <boost/numeric/ublas/storage_sparse.hpp>
|
|
|
|
int main () {
|
|
using namespace boost::numeric::ublas;
|
|
map_std<int, double> a (3);
|
|
for (unsigned i = 0; i < a.size (); ++ i) {
|
|
a [i] = i;
|
|
std::cout << a [i] << std::endl;
|
|
}
|
|
}
|

</pre>

<h2><a name="map_array"></a>Map Array</h2>
|
|
<h4>Description</h4>
|
|
<p>The templated class <code>map_array<I, T, ALLOC></code> implements a <code>std::map</code> like associative container as a sorted array. It therefore some of the Associative Container interface without having the same semantics as an std::map.
|
|
<p>At any time the <code>map_array</code> has a capacity up to which new element can be inserted.
|
|
If <code>insert</code> would cause the size of the <code>map_array</code> to exceeds its capactity then it is <strong>reallocated</strong>. Iterators and reference are invalidated.
|
|
The capacity can be directly control using the <code>reserve</code> member function.
|
|
