Constructors

	Name	Description
	FMallocPoisonProxy ( FMalloc* InMalloc )

Overridden from FMalloc

	Name	Description
void	ClearAndDisableTLSCachesOnCurrentThread()	Clears the TLS caches on the current thread and disables any future caching.
void	DumpAllocatorStats ( FOutputDevice& Ar )	Dumps current allocator stats to the log.
void	Free ( void* Original )	Free
bool	GetAllocationSize ( void* Original, SIZE_T& SizeOut )	If possible determine the size of the memory allocated at the given address
void	GetAllocatorStats ( FGenericMemoryStats& out_Stats )	Writes allocator stats from the last update into the specified destination.
const TCHAR ...	GetDescriptiveName()	Gets descriptive name for logging purposes.
void	InitializeStatsMetadata()	Initializes stats metadata.
bool	IsInternallyThreadSafe()	Returns if the allocator is guaranteed to be thread-safe and therefore doesn't need a unnecessary thread-safety wrapper around it.
void *	Malloc ( SIZE_T Count, uint32 Alignment )	Malloc
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.
void *	Realloc ( void* Original, SIZE_T Count, uint32 Alignment )	Realloc
void	SetupTLSCachesOnCurrentThread()	Set up TLS caches on the current thread. These are the threads that we can trim.
void	Trim ( bool bTrimThreadCaches )	Releases as much memory as possible. Must be called from the main thread.
void	UpdateStats()	Called once per frame, gathers and sets all memory allocator statistics into the corresponding stats.
bool	ValidateHeap()	Validates the allocator's heap

Overridden from FExec

		Name	Description
	bool	Exec ( UWorld* InWorld, const TCHAR* Cmd, FOutputDevice& Ar )	Handles any commands passed in on the command line
