◆ ReadRequest()

IAsyncReadRequest * UE::BulkData::Private::FChunkReadFileHandle::ReadRequest	(	int64	Offset,
		int64	BytesToRead,
		EAsyncIOPriorityAndFlags	PriorityAndFlags = `AIOP_Normal`,
		FAsyncFileCallBack *	CompleteCallback = `nullptr`,
		uint8 *	UserSuppliedMemory = `nullptr`
	)

overridevirtual

Submit an async request and/or wait for an async request

Parameters

Offset	Offset into the file to start reading.
BytesToRead	number of bytes to read. If this request is AIOP_Preache, the size can be anything, even MAX_int64, otherwise the size and offset must be fully contained in the file.
PriorityAndFlags	Priority and flags of the request. If this includes AIOP_FLAG_PRECACHE, then memory will never be returned. The request should always be canceled and waited for, even for a precache request.
CompleteCallback	Called from an arbitrary thread when the request is complete. Can be nullptr, if non-null, must remain valid until it is called. It will always be called.

Returns: A request for the read. This is owned by the caller and must be deleted by the caller.

Implements IAsyncReadFileHandle.

◆ SizeRequest()

IAsyncReadRequest * UE::BulkData::Private::FChunkReadFileHandle::SizeRequest ( FAsyncFileCallBack * CompleteCallback = nullptr )

overridevirtual

Request the size of the file. This is also essentially the existence check.
