GetAllocatorStatsInternal()

void FMallocBinnedCommonBase::GetAllocatorStatsInternal ( FGenericMemoryStats &  OutStats, int64  TotalAllocatedSmallPoolMemory  )

protected

LogLargeAllocation()

void FMallocBinnedCommonBase::LogLargeAllocation ( SIZE_T  Size ) const

inlineprotected

OnMallocInitialized()

void FMallocBinnedCommonBase::OnMallocInitialized ( )

overridevirtual

Notifies the malloc implementation that initialization of all allocators in GMalloc is complete, so it's safe to initialize any extra features that require "regular" allocations

Reimplemented from FMalloc.

Reimplemented in FMallocBinned2.
