Constructor Detail

UnJoinNodeWayAction

public UnJoinNodeWayAction()

Constructs a new UnJoinNodeWayAction.

Method Detail

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Called when the action is executed.

notify

public void notify(java.lang.String msg,
                   int messageType)

Send a notification message.

Parameters:

msg - Message to be sent.

messageType - Nature of the message.

cleanSelectedNodes

private java.util.List<Node> cleanSelectedNodes(java.util.List<Way> selectedWays,
                                                java.util.List<Node> selectedNodes)

Removes irrelevant nodes from user selection. The action can be performed reliably even if we remove : * Nodes not referenced by any ways * When only one way is selected, nodes not part of this way (#10396).

Parameters:

selectedWays - List of user selected way.

selectedNodes - List of user selected nodes.

Returns:

New list of nodes cleaned of irrelevant nodes.

getApplicableWays

static java.util.List<Way> getApplicableWays(java.util.List<Way> selectedWays,
                                             java.util.List<Node> selectedNodes)

Find ways to which the disconnect can be applied. This is the list of ways with more than two nodes which pass through all the given nodes, intersected with the selected ways (if any)

Parameters:

selectedWays - List of user selected ways.

selectedNodes - List of user selected nodes.

Returns:

List of relevant ways

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(), JosmAction.listenToLayerChange()

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
