Detailed Description

common implementation of IMemory interface

This implementation delegates the allocation part to a referred IMemoryAllocator instance.

It is not abstract since it implements the statistics methods but with dummy return values. It could have sense in case we want fast allocators without statistic information.

Its main purpose is to factorize some code for concrete implementations.

Constructor & Destructor Documentation

MemoryCommon ( IMemoryAllocator &  alloc, IMemoryOperations &  ope  )

inline

Constructor.

Parameters

[in]	alloc	: the referred memory allocator.
[in]	ope	: the referred memory operations.

Member Function Documentation

void* calloc ( size_t  nmemb, BlockSize_t  size  )

inlinevirtual

See calloc documentation.

Implements IMemoryAllocator.

inlinevirtual

Get the maximum reached size.

Returns

the maximum used memory (in bytes).

Implements IMemory.

size_t getNbBlocks ( )

inlinevirtual
