MoveToEmpty()

void FMemoryImageAllocatorBase::MoveToEmpty

(

FMemoryImageAllocatorBase &

Other

)

Moves the state of another allocator into this one. Assumes that the allocator is currently empty, i.e. memory may be allocated but any existing elements have already been destructed (if necessary).

Parameters

Other

- The allocator to move the state from. This allocator should be left in a valid empty state.

ResizeAllocation()

		int32	NumElements,
		SIZE_T	NumBytesPerElement,
		uint32	Alignment

		const FTypeLayoutDesc &	TypeDesc,
		int32	NumAllocatedElements,
		uint32	Alignment
