Detailed Description

A class for checkpoint tracking of memory allocations allocated by the HeapAllocator.

Member Function Documentation

void DD::Image::AllocationTracker::setObjAddress ( void *  address)

Called from constructors of tracked objects with their this pointer. This allows us to track the actual object address within an allocated block.

AllocTrackingInfo::Checkpoint DD::Image::AllocationTracker::IncCheckpointIndex ( )
static

Increments the checkpoint index, and returns the new index . This allows test code to determine what was allocated since a particular moment of execution

void DD::Image::AllocationTracker::getAllocationsSince ( AllocTrackingInfo::Checkpoint  checkpoint,
AllocTrackingInfo::Vector &  allocations 
) const

Clears and populates a container of objects describing memory allocations tracked by this tracker, allocated at or since the specified checkpoint
