Detailed Description

AllocationTracker is an abstract base class for objects that track memory.

An Allocator instance may contain a pointer to an AllocationTracker that is invoked whenever a chunk of memory is allocated or deallocated.

virtual size_t ion::base::AllocationTracker::GetActiveAllocationBytesCount ( )

pure virtual

Implemented in ion::base::FullAllocationTracker.

virtual size_t ion::base::AllocationTracker::GetActiveAllocationCount ( )

pure virtual

Returns the number of active allocations or the amount of memory in bytes used by active allocations.

These are not guaranteed to be supported by all derived classes; they may return 0 if not.

Implemented in ion::base::FullAllocationTracker.

virtual size_t ion::base::AllocationTracker::GetAllocatedBytesCount ( )

pure virtual

Returns the total number of memory ever allocated or deallocated, in bytes.

These are not guaranteed to be supported by all derived classes; they may return 0 if not.

Implemented in ion::base::FullAllocationTracker.

virtual size_t ion::base::AllocationTracker::GetAllocationCount ( )

pure virtual

Returns the total number of tracked allocations or deallocations.

Implemented in ion::base::FullAllocationTracker.

virtual size_t ion::base::AllocationTracker::GetDeallocatedBytesCount ( )

pure virtual

Implemented in ion::base::FullAllocationTracker.

virtual size_t ion::base::AllocationTracker::GetDeallocationCount ( )

pure virtual

Implemented in ion::base::FullAllocationTracker.

virtual AllocationSizeTrackerPtr ion::base::AllocationTracker::GetGpuTracker ( )

pure virtual

Implemented in ion::base::FullAllocationTracker.

int ion::base::Shareable::GetRefCount ( ) const

inlineinherited

GetRefCount() is part of the interface necessary for SharedPtr.

virtual void ion::base::AllocationTracker::SetGpuTracker ( const AllocationSizeTrackerPtr & gpu_tracker )

pure virtual

Sets/returns an AllocationSizeTracker instance used to track GPU memory allocations.

Implemented in ion::base::FullAllocationTracker.

virtual void ion::base::AllocationTracker::TrackAllocation	(	const Allocator &	allocator,
		size_t	requested_size,
		const void *	memory
	)

pure virtual

TrackAllocation() is called immediately after an Allocator allocates memory.

It receives a reference to the Allocator that allocated the memory, the requested size, and a pointer to the allocated memory.

Implemented in ion::base::FullAllocationTracker.

virtual void ion::base::AllocationTracker::TrackDeallocation	(	const Allocator &	allocator,
		const void *	memory
	)

pure virtual

TrackDeallocation() is called immediately before an Allocator deallocates memory.

It receives a reference to the Allocator that is deallocating the memory and a pointer to the deallocated memory.

Implemented in ion::base::FullAllocationTracker.
