public SemanticZoomMultiInterpreterImpl()

Default constructor, does nothing.

Method Detail

add

public Interpreter add(Interpreter intrp)

Description copied from interface: MultiInterpreter

Add a stroke interpreter, setting the GraphicalObject the Interpreter is added to, via Interpreter.setAttachedGraphicalObject(GraphicalObject).

Overrides:

add in class DefaultMultiInterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.interpreter.MultiInterpreter

Parameters:

intrp - is the StrokeInterpreter to add.

remove

public Interpreter remove(Interpreter intrp)

Description copied from interface: MultiInterpreter

Remove a stroke Interpreter.

Overrides:

remove in class DefaultMultiInterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.interpreter.MultiInterpreter

Parameters:

intrp - is the StrokeInterpreter to remove.

clearInterpreters

public void clearInterpreters()

handleNewStroke

public void handleNewStroke(NewStrokeEvent evt)

Description copied from class: DefaultMultiInterpreterImpl

Called when a stroke is started. Iterates through the list of contained interpreters, firing the new stroke event, until one of the contained interpreters consumes the event.

Overrides:

handleNewStroke in class DefaultMultiInterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.event.StrokeListener

Parameters:

evt - is the event to handle.

handleUpdateStroke

public void handleUpdateStroke(UpdateStrokeEvent evt)

Description copied from class: DefaultMultiInterpreterImpl

Called when a stroke is updated. Iterates through the list of contained interpreters, firing the update stroke event, until one of the contained interpreters consumes the event.

Overrides:

handleUpdateStroke in class DefaultMultiInterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.event.StrokeListener

See Also:

StrokeListener.handleNewStroke(NewStrokeEvent).

handleSingleStroke

public void handleSingleStroke(SingleStrokeEvent evt)

Description copied from class: DefaultMultiInterpreterImpl

Called when a stroke is finished. Iterates through the list of contained interpreters, firing the single stroke event, until one of the contained interpreters consumes the event.

Overrides:

handleSingleStroke in class DefaultMultiInterpreterImpl

Following copied from interface: edu.berkeley.guir.lib.satin.event.StrokeListener

See Also:

StrokeListener.handleNewStroke(NewStrokeEvent).

clone

public Object clone()

Description copied from class: DefaultMultiInterpreterImpl

Clones this MultiInterpreter.

Overrides:

clone in class DefaultMultiInterpreterImpl

clone

protected SemanticZoomMultiInterpreterImpl clone(SemanticZoomMultiInterpreterImpl im)
