Detailed Description

Interface providing methods for dynamic allocation and memory statistics.

This interface provides most common methods for creating/deleting dynamic allocation buffers.

It also provides information about its inner state (current memory usage, maximum reached).

Specific implementations could be:

  • system allocator (ie. functions from stdlib.h)
  • allocator with a maximum allowed total size
  • etc...

Member Function Documentation

virtual TotalSize_t getCurrentUsage ( )
pure virtual

Get the memory usage by the current process.

Returns
the memory usage (in bytes).

Implemented in MemoryCommon.

virtual TotalSize_t getMaximumUsage ( )
pure virtual

Get the maximum reached size.

Returns
the maximum used memory (in bytes).

Implemented in MemoryCommon.

virtual size_t getNbBlocks ( )
pure virtual

Get the number of currently allocated memory blocks.

Returns
the number of allocated blocks.

Implemented in MemoryCommon.
