public class NodeHidingBehavior
extends AbstractHidingBehavior

The NodeHidingBehavior is specific to NodeContentPart. It registers listeners on the HidingModel upon activation. When the HidingModel changes, the hidden status of the NodeContentPart 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 NodeContentPart.

public NodeHidingBehavior()

Method Detail

activate

public void activate()

Specified by:

activate in interface IActivatable

Overrides:

activate in class AbstractHidingBehavior

createHiddenNeighborsFeedbackPart

protected void createHiddenNeighborsFeedbackPart()

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

deactivate

public void deactivate()

Specified by:

deactivate in interface IActivatable

Overrides:

deactivate in class AbstractHidingBehavior

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.

getHiddenNeighborsFeedbackPart

protected IVisualPart<javafx.scene.Node,? extends javafx.scene.Node> getHiddenNeighborsFeedbackPart()

Returns the HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.

Returns:

The HiddenNeighborsFeedbackPart that is managed by this NodeHidingBehavior.

getHost

public NodeContentPart getHost()

Specified by:

getHost in interface IBehavior<javafx.scene.Node>

Overrides:

getHost in class AbstractBehavior<javafx.scene.Node>

onHidingModelChange

protected void onHidingModelChange(java.beans.PropertyChangeEvent event)

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:

event - The property 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.
