Constructor Detail

AlignInCircleAction

public AlignInCircleAction()

Constructs a new AlignInCircleAction.

Method Detail

createMoveCommand

public static MoveCommand createMoveCommand(Node n,
                                            PolarCoor coor)

Create a MoveCommand to move a node to a PolarCoor.

Parameters:

n - Node to move

coor - polar coordinate where to move the node

Returns:

new MoveCommand

Since:

13107

actionPerformed

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

Perform AlignInCircle action. A fixed node is a node for which it is forbidden to change the angle relative to center of the circle. All other nodes are uniformly distributed. Case 1: One unclosed way. --> allow action, and align selected way nodes If nodes contained by this way are selected, there are fix. If nodes outside from the way are selected there are ignored. Case 2: One or more ways are selected and can be joined into a polygon --> allow action, and align selected ways nodes If 1 node outside of way is selected, it became center If 1 node outside and 1 node inside are selected there define center and radius If no outside node and 2 inside nodes are selected those 2 nodes define diameter In all other cases outside nodes are ignored In all cases, selected nodes are fix, nodes with more than one referrers are fix (first referrer is the selected way) Case 3: Only nodes are selected --> Align these nodes, all are fix

collectNodesWithExternReferers

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

Collect all nodes with more than one referrer.

Parameters:

ways - Ways from witch nodes are selected

Returns:

List of nodes with more than one referrer

collectNodesAnticlockwise

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

Assuming all ways can be joined into polygon, create an ordered list of node.

Parameters:

ways - List of ways to be joined

Returns:

Nodes anticlockwise ordered

actionAllowed

private static boolean actionAllowed(java.util.Collection<Node> nodes)

Check if one or more nodes are outside of download area

Parameters:

nodes - Nodes to check

Returns:

true if action can be done

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()

checkWaysArePolygon

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

Determines if ways can be joined into a polygon.

Parameters:

ways - The ways collection to check

Returns:

true if all ways can be joined into a polygon
