This is a CArrayFixSeg<class T> object whose elements:

all have the same length
are contained within +a segmented array buffer; the elements are logically contiguous but are physically +contiguous only within a segment.

A segmented buffer is implemented as a doubly linked list of equally sized +cells allocated from the heap and is always extended by allocating a new segment +and inserting it into the appropriate place in the list. A segmented array +buffer is implemented using a CBufSeg object.

The following diagram illustrates how elements are organised within the +array buffer:

This kind of array is suitable for large arrays with a high +turnover of elements.

This class is immediately derived from the abstract template base class CArrayFix<class T> which +is itself derived from the abstract non-templated base class CArrayFixBase.
