Constructor Detail

Instance

public Instance(VisualizerContext context,
                VisualizationTask task,
                VisualizationPlot plot,
                double width,
                double height,
                Projection proj)

Constructor.

Parameters:

context - Visualizer context

task - Task

plot - Plot to draw to

width - Embedding width

height - Embedding height

proj - Projection

Method Detail

fullRedraw

public void fullRedraw()

Description copied from interface: Visualization

Request a full redrawing of the visualization.

Specified by:

fullRedraw in interface Visualization

Specified by:

fullRedraw in class AbstractVisualization

incrementalRedraw

public void incrementalRedraw()

Description copied from class: AbstractVisualization

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

Specified by:

incrementalRedraw in interface Visualization

Overrides:

incrementalRedraw in class AbstractVisualization

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

getEpsilonFromY

protected double getEpsilonFromY(double y)

Get epsilon from y-value

Parameters:

y - y-Value

Returns:

epsilon

getYFromEpsilon

protected double getYFromEpsilon(double epsilon)

Get y-value from epsilon

Parameters:

epsilon - epsilon

Returns:

y-Value

startDrag

public boolean startDrag(org.w3c.dom.svg.SVGPoint start,
                         org.w3c.dom.events.Event evt)

Description copied from interface: DragableArea.DragListener

Action to do on drag start.

Specified by:

startDrag in interface DragableArea.DragListener

Parameters:

start - Point where the drag was started.

evt - The event object

Returns:

true to start the drag operation

duringDrag

public boolean duringDrag(org.w3c.dom.svg.SVGPoint start,
                          org.w3c.dom.svg.SVGPoint end,
                          org.w3c.dom.events.Event evt,
                          boolean inside)

Description copied from interface: DragableArea.DragListener

Method called during drags.

Specified by:

duringDrag in interface DragableArea.DragListener

Parameters:

start - Drag starting point

end - Drag end point

evt - The event object

inside - Inside the tracked element

Returns:

true to continue the drag

endDrag

                       boolean inside)

Description copied from interface: DragableArea.DragListener

Method called when a drag was ended.

Specified by:

endDrag in interface DragableArea.DragListener

Parameters:

start - Drag starting point

end - Drag end point

evt - The event object

inside - Whether the end point was inside the area

Returns:

true to complete the drag

unsetEpsilon
