Detailed Description

template<typename T, size_t N, class ExcessAllocator = AllocatorMalloc>
class CS::Memory::LocalBufferAllocator< T, N, ExcessAllocator >

An allocator with a small local buffer.

If the data fits into the local buffer (which is set up to holds N elements of type T), a memory allocation from the heap is saved. Thus, if you have lots of arrays with a relatively small, well known size you can gain some performance by using this allocator.

Warning:
This allocator is designed to work in scenarios where you have at most one block allocated at any time!

The pointer returned may point into the instance data; be careful when moving that around - an earlier allocated pointer may suddenly become invalid!

Remarks:
This means that if you use this allocator with an array, and you nest that into another array, you MUST use csSafeCopyArrayElementHandler for the nesting array!
