TNonFreePooledMemManager class

In unit PooledMM

Memory manager for fixed memory blocks which does not free any memory.

Declaration

pascal

TNonFreePooledMemManager = class

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.

Properties

ItemSize public Size of an item in the list.

`NewItem`	public	Return a pointer to a new memory block.
`EnumerateItems`	public	Enumerate all items in the list.

Fields
