|
||
|
|
<h4>Description</h4>
|
||
|
|
<p>The templated class <code>bounded_array<T, N, ALLOC></code> implements a bounded storage array. The bounded array is similar to a C++ array type in that its maximum size is bounded by N and is allocated on the stack instead of the heap. Similarly a <code>bounded_array</code> requires no secondary storage and ALLOC is only used to specify <code>size_type</code> and <code>difference_type</code>.
|
||
|
|
</p>
|
||
|
|
<p>When resized <code>bounded_array</code> never reallocated the storage. It is therefore always efficient to resize a <code>bounded_array</code> but the size bound N must not be exceeded.</p>
|
||
|
|
<h4>Example</h4>
|
||
|
|
<pre>
|
||
|
|
#include <boost/numeric/ublas/storage.hpp>
|
||
|
|
|
||
|
|
int main () {
|
||
|
|
using namespace boost::numeric::ublas;
|
||
|
|
bounded_array<double, 3> a (3);
|
||
|
|
for (unsigned i = 0; i < a.size (); ++ i) {
|
||
|
|
a [i] = i;
|
||
|
|
std::cout << a [i] << std::endl;
|
||
|
|
}
