Constructors

Constructor and Description
SketchTransducer() This constructor should only be called once, to create the prototype object.
SketchTransducer(SketchModel model) This constructor is called by the newInstance() method, which builds a new transducer for the given sketch model.

Method Summary

Modifier and Type	Method and Description
Object	getTransferData(DataFlavor flavor) Perform recognition on the sketch model and return the transfer data as a string, or as plain text (based on StringSelection's implementation of getTransferData();
DataFlavor[]	getTransferDataFlavors() Return StringSelection's data flavors.
boolean	isDataFlavorSupported(DataFlavor in) Call StringSelection's predicate.
void	lostOwnership(Clipboard clipboard, Transferable contents) Do nothing.
Transducer	newInstance(SketchModel in) Apply the transducer to the given set of strokes by performing sketch recognition on the given strokes.
