## Detailed Description

This class is used to efficiently allocate memory on the heap.

It allows us to allocate small blocks of memory (smaller or equal to 1024 bytes) efficiently. This implementation is inspired by the small block allocator described here : http://www.codeproject.com/useritems/Small_Block_Allocator.asp

## Member Function Documentation

## ◆ allocate()

void * PoolAllocator::allocate | ( | size_t | size | ) |
| overridevirtual

Allocate memory of a given size (in bytes) and return a pointer to the allocated memory.

Implements reactphysics3d::MemoryAllocator.

## ◆ release()

void PoolAllocator::release | ( | void * | pointer,
|  | size_t | size )
| overridevirtual

Release previously allocated memory.

Implements reactphysics3d::MemoryAllocator.
