Detailed Description

Computes the memory allocated between two points in code.

This class allows the user to trace the memory charge between the execution of two pieces of code. It can be started and stopped in order to evaluate the execution over multiple passes. The values of memory are taken from GetProcessMemoryInfo() for Windows, the SMAPS file for Linux and getrusage() otherwise.

Examples:

SphinxExamples/src/Core/Common/TraceMemoryBetweenPoints/Code.cxx.
