Constructor Detail

ThumbnailVisualization

public ThumbnailVisualization(VisFactory visFactory,
                      VisualizationTask task,
                      int mask)

Constructor.

Parameters:

visFactory - Visualizer Factory to use

task - Task to use

mask - Event mask (for auto-updating)

Method Detail

destroy

public void destroy()

Description copied from interface: Visualization

Destroy the visualization. Called after the elements have been removed from the document. Implementations should remove their listeners etc.

Specified by:

destroy in interface Visualization

Overrides:

destroy in class AbstractVisualization

getLayer

public Element getLayer()

Description copied from interface: Visualization

Get the SVG layer of the given visualization.

Specified by:

getLayer in interface Visualization

Overrides:

getLayer in class AbstractVisualization

Returns:

layer

incrementalRedraw

protected void incrementalRedraw()

Redraw the visualization (maybe incremental). Optional - by default, it will do a full redraw, which often is faster!

Overrides:

incrementalRedraw in class AbstractVisualization

redraw

protected void redraw()

Perform a full redraw.

Specified by:

redraw in class AbstractVisualization

doThumbnail

public void doThumbnail()

Description copied from interface: ThumbnailThread.Listener

Callback when to (re-)compute the thumbnail.

Specified by:

doThumbnail in interface ThumbnailThread.Listener

refreshThumbnail

protected void refreshThumbnail()

resultChanged

public void resultChanged(Result current)

Description copied from interface: ResultListener

Notify that the current result has changed substantially.

Specified by:

resultChanged in interface ResultListener

Overrides:

resultChanged in class AbstractVisualization

Parameters:

current - Result that has changed.
