virtual bool BufferedTransformation::Attachable | ( | ) | [inline, virtual, inherited] |
returns whether this object allows attachment
Some BufferedTransformation objects (e.g. Filter objects) allow other BufferedTransformation objects to be attached. When this is done, the first object instead of buffering its output, sents that output to the attached object as input. The entire attachment chain is deleted when the anchor object is destructed.
