Constructor Detail

BpmnIconDecorator

protected BpmnIconDecorator(AbstractBpmnPainter painterDelegate)

Initializes a new BpmnIconDecorator instance.

Parameters:

painterDelegate - the decorated painter.

See Also:

getPainterDelegate()

Method Detail

getPainterDelegate

protected AbstractBpmnPainter getPainterDelegate()

Returns the decorated painter.

Returns:

the decorated painter.

getPaintIconThreshold

public double getPaintIconThreshold()

Delegates to AbstractBpmnPainter.getPaintIconThreshold().

Overrides:

getPaintIconThreshold in class AbstractBpmnPainter

Returns:

the size threshold for displaying the inner icon of this painter.

See Also:

setPaintIconThreshold(double)

setPaintIconThreshold

public void setPaintIconThreshold(double threshold)

Delegates to AbstractBpmnPainter.setPaintIconThreshold(double).

Overrides:

setPaintIconThreshold in class AbstractBpmnPainter

Parameters:

threshold - the size threshold for displaying the inner icon of this painter.

See Also:

getPaintIconThreshold()

paintNode

protected void paintNode(NodeRealizer context,
                         Graphics2D graphics,
                         boolean sloppy)

Paints the delegate and the icon returned by getIconPainter(y.view.NodeRealizer). The size and location of the icon is determined by getIconBoundingBox(y.view.NodeRealizer).

Overrides:

paintNode in class AbstractBpmnPainter

Parameters:

context - the visual representation of the node being painted.

graphics - the graphics context to paint upon.

sloppy - true if a low-detail version of the node should be painted; false if a high-detail version of the node should be painted.

getIconBoundingBox

protected Rectangle2D getIconBoundingBox(NodeRealizer context)

Determines the bounds of the icon that is painted by this decorator. The default implementation calls getIconBoundingBox(y.view.NodeRealizer, java.awt.geom.Rectangle2D).

Parameters:

context - the visual representation of the node being painted.

Returns:

the location and size of the icon is painted by this decorator.

getIconBoundingBox

protected abstract Rectangle2D getIconBoundingBox(NodeRealizer context,
                                                  Rectangle2D availableRegion)

Determines the bounds of the icon that is painted by this decorator. Called from getIconBoundingBox(y.view.NodeRealizer).

Parameters:

context - the visual representation of the node being painted.

availableRegion - the region in which the icon bounds should lie.

Returns:

the location and size of the icon is painted by this decorator.

getIconPainter

protected abstract BpmnIconPainter getIconPainter(NodeRealizer context)

Returns the icon that is painted by this decorator. Called from paintNode(y.view.NodeRealizer, java.awt.Graphics2D, boolean).

Parameters:

context - the visual representation of the node being painted.

Returns:

the icon that is painted by this decorator.
