CLBufferRegion
public CLBufferRegion(java.nio.ByteBuffer container)
Creates aCLBufferRegion
instance at the current position of the specifiedByteBuffer
container. Changes to the buffer's content will be visible to the struct instance and vice versa.The created instance holds a strong reference to the container object.
