Syntax

struct FMipAllocation

Name	Remarks	Include Path
FMipAllocation ()	Create an empty object	Engine/Texture.h
FMipAllocation ( FSharedBuffer SrcData )	Take a read only FSharedBuffer, will allocate a new buffer and copy from this if Read/Write access is requested	Engine/Texture.h
FMipAllocation ( const FMipAllocation& )	Do not actually do anything for copy constructor or assignments, this is required for as long as we need to support the old bulkdata code path (although previously storing these allocations as raw pointers would allow it to be assigned, this would most likely cause a mismatch in lock counts, either in FTextureSource or the underlying bulkdata and was never actually safe)	Engine/Texture.h
FMipAllocation ( FMipAllocation&& )	We do allow rvalue assignment.	Engine/Texture.h

const FSharedBuffer & GetDataReadOnly()	Returns a FSharedBuffer that contains the current texture data but cannot be directly modified	Engine/Texture.h
uint8 * GetDataReadWrite()		Engine/Texture.h
FMutableMemoryView GetDataReadWriteView()	Returns a pointer that contains the current texture data and can be written to	Engine/Texture.h
int64 GetSize()	Returns the overall size of the data in bytes	Engine/Texture.h
bool IsNull()	Returns true if the object contains no data	Engine/Texture.h
FSharedBuffer Release()	Returns the internal FSharedBuffer and relinquish ownership, used to transfer the data to virtualized bulkdata	Engine/Texture.h
void Reset()	Release all currently owned data and return the object to the default state	Engine/Texture.h
