Method Detail

setShapeSet

public void setShapeSet(SimpleSet set)
                 throws VisADException,
                        RemoteException

Sets the SimpleSet that defines the mapping from RealType values to indices into an array of shapes. This method must be called before the setShapes() method to avoid a subsequent NullPointerException in the running of the display.

Parameters:

set - 1-D set of values that defines the mapping from RealType values to indices into the array of shapes. The domain dimension shall be 1.

Throws:

VisADException

RemoteException

setShape

public void setShape(int index,
                     VisADGeometryArray shape)
              throws VisADException,
                     RemoteException

set the shape associated with index; the VisADGeometryArray class hierarchy defines various kinds of shapes

Throws:

VisADException

RemoteException

setShapes

public void setShapes(VisADGeometryArray[] shs)
               throws VisADException,
                      RemoteException

Sets the array of shapes. The array is accessed by index determined from the value-to-index mapping established by the setShapeSet() method. The VisADGeometryArray class hierarchy defines various kinds of shapes. This method must be called after the setShapeSet() method to avoid a subsequent NullPointerException in the running of the display.

Parameters:

shs - The array of shapes.

Throws:

VisADException

RemoteException

getShapes

public VisADGeometryArray[] getShapes(float[] values)
                               throws VisADException

Throws:

VisADException

setScale

public void setScale(float s)
              throws VisADException,
                     RemoteException

Throws:

VisADException

RemoteException

getScale

public float getScale()

getSaveString

public String getSaveString()

get a string that can be used to reconstruct this control later

Specified by:

getSaveString in class Control

Returns:

String representation of this Control

setSaveString

public void setSaveString(String save)
                   throws VisADException,
                          RemoteException

reconstruct this control using the specified save string

Specified by:

setSaveString in class Control

Parameters:

save - - String representation for reconstruction

Throws:

VisADException - if a VisAD error occurs

RemoteException - if an RMI error occurs

syncControl

public void syncControl(Control rmt)
                 throws VisADException

copy the state of a remote control to this control

Specified by:

syncControl in class Control

Parameters:

rmt - remote Control whose state is copied

Throws:

VisADException - if a VisAD error occurs

setAutoScale

public void setAutoScale(boolean auto)
                  throws VisADException

Throws:

VisADException

nullControl

public void nullControl()

Description copied from class: Control

end this control (called by ScalarMap.nullDisplay())

Overrides:

nullControl in class Control

equals

public boolean equals(Object o)

Description copied from class: Control

Indicates whether or not this instance equals an Object

Overrides:

equals in class Control

Parameters:

o - an Object

Returns:

true if and only if this instance is equal to o

clone

public Object clone()

Overrides:

clone in class Control

Returns:

a copy of this Control
