<h2>Resizing an Array</h2>
|
||||
|
||||
The <tt>boost::multi_array</tt> class provides an element-preserving
|
||||
resize operation. The number of dimensions must remain the same, but
|
||||
the extent of each dimension may be increased and decreased as
|
||||
desired. When an array is made strictly larger, the existing elements
|
||||
will be preserved by copying them into the new underlying memory and
|
||||
subsequently destructing the elements in the old underlying memory.
|
||||
Any new elements in the array are default constructed. However, if
|
||||
the new array size shrinks some of the dimensions, some elements will
|
||||
no longer be available.
|
||||
|
||||
<h3>Example</h3>
|
||||
<blockquote>
|
||||
<pre>
|
||||
typedef boost::multi_array<int, 3> array_type;
|
||||
|
||||
array_type::extent_gen extents;

||||
array_type A(extents[3][3][3]);

||||
A[0][0][0] = 4;
|
||||
A[2][2][2] = 5;
|
||||
A.resize(extents[2][3][4]);

||||
assert(A[0][0][0] == 4);
|
||||
// A[2][2][2] is no longer valid.
