public abstract class AbstractLayoutBehavior
extends AbstractBehavior<javafx.scene.Node>

The AbstractLayoutBehavior is an abstract behavior that schedules preLayout() and postLayout() to be called before or after a layout pass, respectively. The preLayout() method can be used to write layout information into the layout model. Similarly, the postLayout() method can be used to read layout information from the layout model.

Returns:

The GraphLayoutContext for which preLayout() and postLayout() shall be called before or after a layout pass, respectively.

postLayout

protected abstract void postLayout()

Called after a layout pass. Should be used to transfer layout information from the layout model over to the visualization.

preLayout

protected abstract void preLayout()

Called before a layout pass. Should be used to transfer layout information from the visualization over to the layout model.
