Class AstFigureStore

java.lang.Object

uk.ac.starlink.diva.DrawFigureStore

uk.ac.starlink.ast.gui.AstFigureStore

All Implemented Interfaces:

FigureStore, StoreSource

public class AstFigureStore
extends DrawFigureStore

A subclass of DrawFigureStore that adds functionality to store and restore the current AST context along with the properties of a set of figures. This is intended to make it possible to save figures and restore them using world coordinates, not just graphics coordinates (so that figures can be redrawn at the same wavelength, time, celestial coordinates etc.).

Constructor Detail

AstFigureStore

public AstFigureStore(AstPlotSource plotSource,
                      String application,
                      String storeFile,
                      String tagName)

Constructor.

Parameters:

plotSource - the source of the Plot currently being used to map world coordinates to graphics coordinates. It is expected that the Plot will be re-created so access needs to be provided in this form.

application - the name of the application directory used for backing store files (created in "home" directory).

storeFile - file used for storing figures (in application specific directory).

tagName - the name of the tag (root element) that contains figures that can be restored by this object.

Method Detail

saveState

public void saveState(Element rootElement)

Description copied from class: DrawFigureStore

Save all the figures currently held by the DrawActions to the given root element.

Specified by:

saveState in interface StoreSource

Overrides:

saveState in class DrawFigureStore

restoreState

public void restoreState(Element rootElement)

Description copied from class: DrawFigureStore

Restore a previous saved state to the DrawActions object. These are then repainted by any GraphicsPanes that are associated with the DrawActions instance.

Specified by:

restoreState in interface StoreSource

Overrides:

restoreState in class DrawFigureStore

savePlot

protected void savePlot(Element rootElement)

restorePlot

protected Plot restorePlot(Element rootElement)
