Constructor Detail

SelectValueScalarMap

public SelectValueScalarMap(visad.RealType realType,
                            DisplayAdapter display)
                     throws visad.VisADException,
                            java.rmi.RemoteException

Constructs.

Parameters:

realType - The type of data to be value-selected.

display - The adapted, VisAD display for rendering.

Throws:

visad.VisADException - VisAD failure.

java.rmi.RemoteException - Java RMI failure.

Method Detail

setValue

public final void setValue(float value)
                    throws java.rmi.RemoteException,
                           visad.VisADException

Sets the selection value. This method fires a PropertyChangeEvent for VALUE 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:

value - The selection value.

Throws:

visad.VisADException - VisAD failure.

java.rmi.RemoteException - Java RMI failure.

setValue

public final void setValue(visad.Real value)
                    throws visad.UnitException,
                           java.rmi.RemoteException,
                           visad.VisADException

Sets the selection value. This method fires a PropertyChangeEvent for VALUE 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:

value - The selection value.

Throws:

visad.UnitException - The unit of the given value is not convertible to the unit of the data type.

visad.VisADException - VisAD failure.

java.rmi.RemoteException - Java RMI failure.
