@class Memory::PoolArrayAllocator
|
||
|
|
|
||
|
|
Allocates small memory blocks from an array of fixed-size memory pools.
|
||
|
|
Bigger allocation go directly through to a heap. Note that when
|
||
|
|
freeing a memory block, there are 2 options: one with providing
|
||
|
|
the size of the memory block (which is probably a bit faster) and
|
||
|
|
one conventional without providing the size.
