Detailed Description
template<class T>
class CArrayVarSeg< T >
class CArrayVarSeg< T >
Array of variable length objects implemented using a segmented dynamic buffer.
The elements of the array are instances of the template class T and are contained within their own heap cells. Pointers to the elements are maintained within a segmented dynamic buffer, a CBufSeg.
The elements can be T or R type objects and must have an accessible default constructor.

Note that no memory is allocated to the array buffer by this constructor.
- Parameters
-
aGranularity The granularity of the array.
Panic condition: E32USER-CBase 19, if aGranularity is not positive.
