All Implemented Interfaces:

IActivatable, IAdaptable.Bound<IVisualPart<? extends Node>>, IBehavior

public class NodeHidingBehavior
extends AbstractHidingBehavior

The NodeHidingBehavior is specific to NodePart. It registers listeners on the HidingModel upon activation. When the HidingModel changes, the hidden status of the NodePart is determined. If the hidden status of the part changed, either AbstractHidingBehavior.hide() or AbstractHidingBehavior.show() will be called, respectively, to hide/show the part. Additionally, a HiddenNeighborsFeedbackPart is managed by this NodeHidingBehavior. The HiddenNeighborsFeedbackPart shows the number of hidden neighbors of the NodePart.

Method Details

createHiddenNeighborsFeedbackPart

protected void createHiddenNeighborsFeedbackPart()

Creates the HiddenNeighborsFeedbackPart that shows the hidden neighbors of the NodePart on which this NodeHidingBehavior is installed.

determineHiddenStatus

protected boolean determineHiddenStatus()

Description copied from class: AbstractHidingBehavior

Returns true if the host is currently hidden. Otherwise, returns false.

Specified by:

determineHiddenStatus in class AbstractHidingBehavior

Returns:

true if the host is currently hidden, otherwise false.

doActivate

protected void doActivate()

Overrides:

doActivate in class AbstractHidingBehavior

doDeactivate

protected void doDeactivate()

Overrides:

doDeactivate in class AbstractHidingBehavior

getHiddenNeighborsFeedbackPart

protected IVisualPart<? extends Node> getHiddenNeighborsFeedbackPart()

Returns the HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.

Returns:

The HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.

getHost

public NodePart getHost()

Specified by:

getHost in interface IBehavior

Overrides:

getHost in class AbstractBehavior

onHidingModelChange

protected void onHidingModelChange(SetChangeListener.Change<? extends Node> change)

Description copied from class: AbstractHidingBehavior

Called upon HidingModel changes. Determines if the host is now hidden using AbstractHidingBehavior.determineHiddenStatus() and compares the result with the previous hidden status. If the host was previously hidden and is not hidden anymore, AbstractHidingBehavior.show() is called. Otherwise, AbstractHidingBehavior.hide() is called.

Overrides:

onHidingModelChange in class AbstractHidingBehavior

Parameters:

change - The change event of the HidingModel.

removeHiddenNeighborsFeedbackPart

protected void removeHiddenNeighborsFeedbackPart()

Removes the HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.

updateHiddenNeighborsFeedbackPart

protected void updateHiddenNeighborsFeedbackPart()

Refreshes the HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.
