Provides support for adapting ScalarMap-s for 2-D contour lines.

Instances of this class have the following, bound, JavaBean properties:

Name	Type	Access	Default	Description
contourLevels	ContourLevels	set/get	empty-set of levels	The contour levels of this instance
labeling	boolean	set/get	false	Whether or not contour-line labeling is enabled

Constructor Details

ContourScalarMap

public ContourScalarMap(RealType realType,
 DisplayAdapter display)
                 throws VisADException,
RemoteException

Constructs.

Parameters:

realType - The type of data that is to be contoured.

display - The adapted VisAD display on which to contour the data.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Details

setLabeling

public final void setLabeling(boolean on)
                       throws VisADException,
RemoteException

Sets the labeling of contour lines. This method fires a PropertyChangeEvent for LABELING with this instance as the source and the old and new values appropriately set. The event is fired synchronously -- so watch out for deadlock.

Parameters:

on - Whether or not the contour lines should be labeled.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

isLabeling

public final boolean isLabeling()

Indicates whether or not contour-line labeling is enabled.

Returns:

true if and only if the contour lines are labeled.

setRange

public void setRange(float min,
 float max)
              throws RemoteException,
VisADException

Sets the range of data to be contoured.

Parameters:

min - The minimum, possible data value to be considered

max - The maximum, possible data value to be considered

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

setContourLevels

public final void setContourLevels(ContourLevels contourLevels)
                            throws RemoteException,
VisADException

Sets the contour values. This method fires a PropertyChangeEvent for CONTOUR_LEVELS with this instance as the source and the old and new values appropriately set. The firing is done synchronously -- so watch out for deadlock.

Parameters:

contourLevels - The contour values.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

See Also:

• CONTOUR_LEVELS

getContourLevels

public final ContourLevels getContourLevels()

Returns the contour levels.

Returns:

The Contour levels. The initial value is an empty set of levels.

setControl

protected void setControl()
                   throws VisADException,
RemoteException

Sets the control of the underlying ScalarMap. This is a template method.

Specified by:

setControl in class ScalarMapAdapter

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.
