All Implemented Interfaces:

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

public final class AlignInLineAction
extends JosmAction

Aligns all selected nodes into a straight line (useful for roads that should be straight, but have side roads and therefore need multiple nodes) Case 1: Only ways selected, align each ways taking care of intersection. Case 2: Single node selected, align this node relative to the surrounding nodes. Case 3: Single node and ways selected, align this node relative to the surrounding nodes only parts of selected ways. Case 4: Only nodes selected, align these nodes respect to the line passing through the most distant nodes.

Method Summary

Modifier and Type	Method and Description
void	actionPerformed(java.awt.event.ActionEvent e) Operation depends on the selected objects:
private Command	alignMultiWay(java.util.Collection<Way> ways) Align way in case of multiple way #6819
private Command	alignOnlyNodes(java.util.List<Node> nodes) Align nodes in case that only nodes are selected The general algorithm here is to find the two selected nodes that are furthest apart, and then to align all other selected nodes onto the straight line between these nodes.
private Command	alignSingleNode(Node node, java.util.List<AlignInLineAction.Line> lines) Align a single node relative to a set of lines #9081
private java.util.List<AlignInLineAction.Line>	getInvolvedLines(Node node, java.util.List<Way> refWays) Get lines useful to do alignment of a single node
private void	nodePairFurthestApart(java.util.List<Node> nodes, Node[] resultOut) Compute 2 anchor points to align a set of nodes.
protected void	updateEnabledState() Override in subclasses to update the enabled state of the action when something in the JOSM state changes, i.e.
protected void	updateEnabledState(java.util.Collection<? extends OsmPrimitive> selection) Override in subclasses to update the enabled state of the action if the collection of selected primitives changes.

AlignInLineAction

public AlignInLineAction()

Constructs a new AlignInLineAction.

Method Detail

nodePairFurthestApart

private void nodePairFurthestApart(java.util.List<Node> nodes,
                                   Node[] resultOut)

Compute 2 anchor points to align a set of nodes. If all nodes are part of a same way anchor points are choose farthest relative to this way, else choose farthest nodes.

Parameters:

nodes - Nodes to be aligned

resultOut - Array of size >= 2

actionPerformed

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

Operation depends on the selected objects:

alignOnlyNodes

private Command alignOnlyNodes(java.util.List<Node> nodes)
                        throws AlignInLineAction.InvalidSelection

Align nodes in case that only nodes are selected The general algorithm here is to find the two selected nodes that are furthest apart, and then to align all other selected nodes onto the straight line between these nodes.

Parameters:

nodes - Nodes to be aligned

Returns:

Command that perform action

Throws:

AlignInLineAction.InvalidSelection

alignMultiWay

private Command alignMultiWay(java.util.Collection<Way> ways)
                       throws AlignInLineAction.InvalidSelection

Align way in case of multiple way #6819

Parameters:

ways - Collection of way to align

Returns:

Command that perform action

Throws:

AlignInLineAction.InvalidSelection

getInvolvedLines

private java.util.List<AlignInLineAction.Line> getInvolvedLines(Node node,
                                                                java.util.List<Way> refWays)
                                                         throws AlignInLineAction.InvalidSelection

Get lines useful to do alignment of a single node

Parameters:

node - Node to be aligned

refWays - Ways where useful lines will be searched

Returns:

List of useful lines

Throws:

AlignInLineAction.InvalidSelection

alignSingleNode

private Command alignSingleNode(Node node,
                                java.util.List<AlignInLineAction.Line> lines)
                         throws AlignInLineAction.InvalidSelection

Align a single node relative to a set of lines #9081

Parameters:

node - Node to be aligned

lines - Lines to align node on

Returns:

Command that perform action

Throws:

AlignInLineAction.InvalidSelection

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
