Constructor Detail

SemanticZoomInterpreterWrapper

public SemanticZoomInterpreterWrapper()

Empty constructor, does nothing.

SemanticZoomInterpreterWrapper

public SemanticZoomInterpreterWrapper(Interpreter newintrp,
                                      double startSc,
                                      double endSc)

SemanticZoomInterpreterWrapper

public SemanticZoomInterpreterWrapper(Interpreter newintrp)

Wrap an interpreter. By default, this semantic zoom wrapper is active from zoom scale 0 to infinity.

SemanticZoomInterpreterWrapper

public SemanticZoomInterpreterWrapper(SemanticZoomInterpreterWrapper w)

A copy constructor, deep.

Method Detail

setRange

public void setRange(double start,
                     double end)

getStartScale

public double getStartScale()

getEndScale

public double getEndScale()

isEnabled

public boolean isEnabled()

See if we are currently enabled AND in a valid zoom range.

Overrides:

isEnabled in class InterpreterWrapper

getAbsoluteScaleFactor

protected double getAbsoluteScaleFactor()

handleNewStroke

public void handleNewStroke(NewStrokeEvent evt)

Active if and only if we are in the right scale range.

Overrides:

handleNewStroke in class InterpreterImpl

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

Parameters:

evt - is the event to handle.

handleUpdateStroke

public void handleUpdateStroke(UpdateStrokeEvent evt)

Active if and only if we are in the right scale range.

Overrides:

handleUpdateStroke in class InterpreterImpl

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

See Also:

StrokeListener.handleNewStroke(NewStrokeEvent).

handleSingleStroke

public void handleSingleStroke(SingleStrokeEvent evt)

Active if and only if we are in the right scale range.

Overrides:

handleSingleStroke in class InterpreterImpl

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

See Also:

StrokeListener.handleNewStroke(NewStrokeEvent).

clone

public Object clone()

Description copied from class: InterpreterImpl

Since not overriding clone() can cause many errors with copying-and-pasting, I'm forcing you to do it. So there.

Overrides:

clone in class InterpreterImpl

clone

protected SemanticZoomInterpreterWrapper clone(SemanticZoomInterpreterWrapper iw)

toString

public String toString()

Overrides:

toString in class InterpreterWrapper
