Detailed Description

Heap Allocator

This is a very simple, thread-safe Heap allocator which calls through to DD::Image::Memory and tracks how much memory its using. Additionally, if FN_TRACK_MEMORY_ALLOCATIONS is defined (in Memory.h), and the NUKE_TRACK_OBJECT_ALLOCATIONS environment variable is set to 1, allocations using this allocator will be tracked between checkpoints, so that leaks can be identified. See the _nuke_internal.memAllocCheckpoint()/memAllocInfo() Python API calls for details.

Member Function Documentation

◆ setObjAddress()

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

Called from constructors of objects allocated using this allocator with their this pointer. This allows the allocation tracker to track the actual object address within an allocated block.

◆ getName()

const char * DD::Image::HeapAllocator::getName ( ) const
overridevirtual

Implements DD::Image::IAllocator.

◆ getType()

const char * DD::Image::HeapAllocator::getType ( ) const
overridevirtual

Implements DD::Image::IAllocator.

◆ getRequestedUsage()

size_t DD::Image::HeapAllocator::getRequestedUsage ( ) const
overridevirtual

Implements DD::Image::IAllocator.

◆ getRequestedHighWaterMark()

size_t DD::Image::HeapAllocator::getRequestedHighWaterMark ( ) const
overridevirtual

Implements DD::Image::IAllocator.

◆ resetHighWaterMark()

void DD::Image::HeapAllocator::resetHighWaterMark ( )
overridevirtual

Implements DD::Image::IAllocator.
