Description

TNonFreePooledMemManager keeps a list of fixed-size memory blocks in memory. Each block has the same size, making it suitable for storing a lot of records of the same type. It does not free the items stored in it, except when the list is cleared as a whole.

It allocates memory for the blocks in a exponential way, i.e. each time a new block of memory must be allocated, it's size is the double of the last block. The first block will contain 8 items.
