Class PurgeAction

java.lang.Object

javax.swing.AbstractAction

org.openstreetmap.josm.actions.JosmAction

org.openstreetmap.josm.actions.PurgeAction

All Implemented Interfaces:

java.awt.event.ActionListener, java.io.Serializable, java.lang.Cloneable, java.util.EventListener, javax.swing.Action, Destroyable

public class PurgeAction
extends JosmAction

The action to purge the selected primitives, i.e. remove them from the data layer, or remove their content and make them incomplete. This means, the deleted flag is not affected and JOSM simply forgets about these primitives. This action is undo-able. In order not to break previous commands in the undo buffer, we must re-add the identical object (and not semantically equal ones).

updateEnabledState

protected void updateEnabledState()

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e. when a layer is removed or added. See JosmAction.updateEnabledState(Collection) to respond to changes in the collection of selected primitives. Default behavior is empty.

Overrides:

updateEnabledState in class JosmAction

See Also:

JosmAction.updateEnabledState(Collection), JosmAction.initEnabledState()

updateEnabledState

protected void updateEnabledState(java.util.Collection<? extends OsmPrimitive> selection)

Description copied from class: JosmAction

Override in subclasses to update the enabled state of the action if the collection of selected primitives changes. This method is called with the new selection.

Overrides:

updateEnabledState in class JosmAction

Parameters:

selection - the collection of selected primitives; may be empty, but not null
