Constructor & Destructor Documentation

BufferBinder() [1/3]

KisOpenGLBufferCircularStorage::BufferBinder::BufferBinder	(	KisOpenGLBufferCircularStorage *	bufferStorage,
		const void **	dataPtr,
		int	dataSize )

When bufferStorage is non-null, fetches the next buffer from the circular storage, binds it and loads the provided data into the buffer. After loading the data pointer *dataPtr is reset to null to signal that glTexImage2D should not be provided with any pointer.

When bufferStorage is null, the binder does nothing, the data pointer *dataPtris kept unchanged.
