Method Detail

setManipulable

public void setManipulable(boolean manip)
                    throws VisADException,
                           RemoteException

set if area probe can be moved by the user with mouse cursor or not

Parameters:

manip - boolean true if can move

Throws:

RemoteException - Java RMI error

VisADException - VisAD error

getAreaType

public static RealTupleType getAreaType()
                                 throws VisADException,
                                        RemoteException

Get the MathType of the area

Returns:

area's RealTupleType

Throws:

RemoteException - Java RMI error

VisADException - VisAD error

getArea

public RealTuple getArea()
                  throws VisADException,
                         RemoteException

Get the Area as a RealTuple

Returns:

the area as a RealTuple

Throws:

RemoteException - Java RMI error

VisADException - VisAD error

setAutoSize

public void setAutoSize(boolean yesorno)
                 throws VisADException,
                        RemoteException

Set whether the marker should automatically resize as the display is zoomed.

Overrides:

setAutoSize in class SelectorDisplayable

Parameters:

yesorno - true to automatically resize the marker.

Throws:

RemoteException - Java RMI error

VisADException - VisAD error

setPosition

public void setPosition(double x1,
                        double y1,
                        double x2,
                        double y2)
                 throws VisADException,
                        RemoteException

Sets the position of the probe. This method fires a PropertyChangeEvent for SelectorDisplayable.PROPERTY_POSITION.

This implementation uses setPosition(RealTuple) to actually set the position of the probe.

Parameters:

x1 - x position of the upper left corner

y1 - y position of the upper left corner

x2 - x position of the lower right corner

y2 - y position of the lower right corner

Throws:

VisADException - if a VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.

setPosition

public void setPosition(RealTuple position)
                 throws VisADException,
                        RemoteException

Sets the position of the probe. This method fires a PropertyChangeEvent for SelectorDisplayable.PROPERTY_POSITION.

Parameters:

position - The position of the probe.

Throws:

NullPointerException - if the argument is null.

VisADException - if position.getType().equals( RealTupleType.SpatialCartesian2DTuple) is false or if another VisAD failure occurs.

RemoteException - if a Java RMI failure occurs.
