Constructor Detail

SelectValueScalarMap

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

Constructs.

Parameters:

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

display - The adapted, VisAD display for rendering.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Detail

setValue

public final void setValue(float value)
                    throws RemoteException,
                           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:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

setValue

public final void setValue(Real value)
                    throws UnitException,
                           RemoteException,
                           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:

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

VisADException - VisAD failure.

RemoteException - Java RMI failure.

getValue

public final Real getValue()

Returns the selection value.

Returns:

The selection value.

setControl

protected void setControl()
                   throws VisADException,

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.
