Public Virtual

Overridden from FMalloc

Name Remarks Include Path Unreal Specifiers

virtual void ClearAndDisableTLSCachesOnCurrentThread()

 Clears the TLS caches on the current thread and disables any future caching. HAL/MallocBinnedGPU.h  

virtual void DumpAllocatorStats ( FOutputDevice& Ar
)

 Dumps current allocator stats to the log. HAL/MallocBinnedGPU.h  

virtual void Free ( void* Original
)

 Free HAL/MallocBinnedGPU.h  

virtual bool GetAllocationSize ( void* Original,
SIZE_T& SizeOut
)

 If possible determine the size of the memory allocated at the given address HAL/MallocBinnedGPU.h  

virtual void GetAllocatorStats ( FGenericMemoryStats& out_Stats
)

 Writes allocator stats from the last update into the specified destination. HAL/MallocBinnedGPU.h  

virtual const TCHAR * GetDescriptiveName()

 Gets descriptive name for logging purposes. HAL/MallocBinnedGPU.h  

virtual bool IsInternallyThreadSafe()

 Returns if the allocator is guaranteed to be thread-safe and therefore doesn't need a unnecessary thread-safety wrapper around it. HAL/MallocBinnedGPU.h  

virtual void * Malloc ( SIZE_T Count,
uint32 Alignment
)

 Malloc HAL/MallocBinnedGPU.h  

virtual SIZE_T QuantizeSize ( SIZE_T Count,
uint32 Alignment

 For some allocators this will return the actual size that should be requested to eliminate internal fragmentation. HAL/MallocBinnedGPU.h  

virtual void * Realloc ( void* Original,
SIZE_T Count,
uint32 Alignment
)

 Realloc HAL/MallocBinnedGPU.h  

virtual void SetupTLSCachesOnCurrentThread()

 Set up TLS caches on the current thread. These are the threads that we can trim. HAL/MallocBinnedGPU.h  

virtual void Trim ( bool bTrimThreadCaches
)

 Releases as much memory as possible. Must be called from the main thread. HAL/MallocBinnedGPU.h  

virtual bool ValidateHeap()

 Validates the allocator's heap HAL/MallocBinnedGPU.h
