Constructor Detail

CrossHair

public CrossHair(String name,
                 RealTupleType polarType)
          throws RemoteException,
                 VisADException

Constructs from a Displayable name and the type of the polar coordinate system.

Parameters:

name - The name for the Displayable.

polarType - The type of the (rho, theta) polar coordinate system.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

CrossHair

protected CrossHair(CrossHair that)
             throws RemoteException,
                    VisADException

Constructs from another instance.

Parameters:

that - The other instance.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Detail

setHairs

public void setHairs(Real maximum)
              throws VisADException,
                     RemoteException

Sets the cross-hairs according to the maximum distance from the center.

Parameters:

maximum - The maximum distance from the center.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

setHairs

public void setHairs(CrossHair crossHair)
              throws VisADException,
                     RemoteException

Sets the cross-hairs according to another CrossHair.

Parameters:

crossHair - The other cross-hair.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

public boolean equals(Object obj)

Indicates if this CrossHair is semantically identical to another object.

Overrides:

equals in class PolarLineDrawing

Parameters:

obj - The other object.

Returns:

true if and only if this CrossHair is semantically identical to obj.

addScalarMaps

public void addScalarMaps(LocalDisplay display)

Adds this instance's ScalarMaps to a display. This implementation does nothing.

Parameters:

display - The display to which to add the ScalarMap-s.

cloneForDisplay

public Displayable cloneForDisplay()
                            throws RemoteException,
                                   VisADException

Returns a clone of this instance suitable for another VisAD display. Underlying data objects are not cloned.

Overrides:

Returns:

A semi-deep clone of this instance.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.
