Cpl::Memory::Pool_ Class Reference

This private concrete class implements a Memory Allocator using a pool of fixed size blocks. More...

Detailed Description

This private concrete class implements a Memory Allocator using a pool of fixed size blocks.

The implementation relies on a sub-class to allocate the actual memory for the blocks.
