Method Detail

init

public boolean init(ucar.unidata.data.DataChoice dataChoice)
             throws visad.VisADException,
                    java.rmi.RemoteException

Description copied from class: ucar.unidata.idv.control.DisplayControlImpl

Initialize this instance according to a data choice. Subclasses should override this method. Overridding methods should probably invoke DisplayControlImpl.setData(DataChoice) as part of their initialization procedure -- although it is unclear when this is actually necessary.

This implementation simply returns true.

Overrides:

init in class ucar.unidata.idv.control.DisplayControlImpl

Parameters:

dataChoice - A data choice or null.

Returns:

true if and only if this instance was correctly initialized by the data choice.

Throws:

visad.VisADException - if a VisAD Failure occurs.

java.rmi.RemoteException - if a Java RMI failure occurs.

initDone

public void initDone()

Description copied from class: ucar.unidata.idv.control.DisplayControlImpl

Called after all initialization has been done. A hook that allows derived classes to do any further initialization.

Overrides:

initDone in class ucar.unidata.idv.control.DisplayControlImpl

getDataProjection

public visad.georef.MapProjection getDataProjection()

Description copied from class: ucar.unidata.idv.control.DisplayControlImpl

get MapProjection of data to display

Specified by:

getDataProjection in interface ucar.unidata.idv.DisplayControl

Overrides:

getDataProjection in class ucar.unidata.idv.control.DisplayControlImpl

Returns:

The native projection of the data

getZeroOutArray

public float[][] getZeroOutArray(float[][] array)

getInitialColorTable

protected ucar.unidata.util.ColorTable getInitialColorTable()

Description copied from class: ucar.unidata.idv.control.DisplayControlImpl

A hook so derived classes can return a colortable. This method uses the DisplayConventions to get the color table based on the paramName

Overrides:

getInitialColorTable in class ucar.unidata.idv.control.DisplayControlImpl

Returns:

The color table to use

doMakeContents

public java.awt.Container doMakeContents()

Description copied from class: ucar.unidata.idv.control.DisplayControlImpl

Make Gui contents

Overrides:

doMakeContents in class ucar.unidata.idv.control.DisplayControlImpl

Returns:

User interface contents
