Constructor Detail

CombineWayAction

public CombineWayAction()

Constructs a new CombineWayAction.

Method Detail

confirmChangeDirectionOfWays

protected static boolean confirmChangeDirectionOfWays()

warnCombiningImpossible

protected static void warnCombiningImpossible()

getTargetWay

protected static Way getTargetWay(java.util.Collection<Way> combinedWays)

combineWaysWorker

public static Pair<Way,Command> combineWaysWorker(java.util.Collection<Way> ways)
                                                 throws UserCancelException

Combine multiple ways into one.

Parameters:

ways - the way to combine to one way

Returns:

null if ways cannot be combined. Otherwise returns the combined ways and the commands to combine

Throws:

UserCancelException - if the user cancelled a dialog.

detectReversedWays

protected static void detectReversedWays(java.util.Collection<Way> ways,
                                         java.util.List<Node> path,

                                         java.util.List<Way> unreversedWays)

tryJoin

protected static java.util.List<Node> tryJoin(java.util.Collection<Way> ways)

joinWithMultipolygonCode

private static java.util.List<Node> joinWithMultipolygonCode(java.util.Collection<Way> ways)

Use Multipolygon.joinWays(Collection) to join ways.

Parameters:

ways - the ways

Returns:

List of nodes of the combined ways or null if ways could not be combined to a single way. Result may contain overlapping segments.

actionPerformed

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

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

See Also:

JosmAction.updateEnabledState(), JosmAction.initEnabledState(), JosmAction.listenToSelectionChange()

checkAndConfirmCombineOutlyingWays

private static boolean checkAndConfirmCombineOutlyingWays(java.util.Collection<Way> ways)

Check whether user is about to combine ways with unknown parents. Request confirmation if he is.

Parameters:

ways - the primitives to operate on

Returns:

true, if operating on outlying primitives is OK; false, otherwise
