public class UnGlueAction
extends JosmAction

Duplicate nodes that are used by multiple ways. Resulting nodes are identical, up to their position. This is the opposite of the MergeNodesAction. If a single node is selected, it will copy that node and remove all tags from the old one

UnGlueAction

public UnGlueAction()

Create a new UnGlueAction.

Method Detail

actionPerformed

public void actionPerformed(ActionEvent e)

Called when the action is executed. This method does some checking on the selection and calls the matching unGlueWay method.

unglueOneNodeAtMostOneWay

private void unglueOneNodeAtMostOneWay(ActionEvent e)

Assumes there is one tagged Node stored in selectedNode that it will try to unglue. (i.e. copy node and remove all tags from the old one. Relations will not be removed)

Parameters:

e - event that trigerred the action

checkForUnglueNode

private boolean checkForUnglueNode(Collection<? extends OsmPrimitive> selection)

Checks if selection is suitable for ungluing. This is the case when there's a single, tagged node selected that's part of at least one way (ungluing an unconnected node does not make sense. Due to the call order in actionPerformed, this is only called when the node is only part of one or less ways.

Parameters:

selection - The selection to check against

Returns:

true if selection is suitable

checkSelectionOneNodeAtMostOneWay

private boolean checkSelectionOneNodeAtMostOneWay(Collection<? extends OsmPrimitive> selection)

Checks if the selection consists of something we can work with. Checks only if the number and type of items selected looks good. If this method returns "true", selectedNode and selectedWay will be set. Returns true if either one node is selected or one node and one way are selected and the node is part of the way. The way will be put into the object variable "selectedWay", the node into "selectedNode".

Parameters:

selection - selected primitives

Returns:

true if either one node is selected or one node and one way are selected and the node is part of the way

checkSelectionOneWayAnyNodes

private boolean checkSelectionOneWayAnyNodes(Collection<? extends OsmPrimitive> selection)

Checks if the selection consists of something we can work with. Checks only if the number and type of items selected looks good. Returns true if one way and any number of nodes that are part of that way are selected. Note: "any" can be none, then all nodes of the way are used. The way will be put into the object variable "selectedWay", the nodes into "selectedNodes".

Parameters:

selection - selected primitives

Returns:

true if one way and any number of nodes that are part of that way are selected

modifyWay

private static Way modifyWay(Node originalNode,
                             Way w,
                             List<Command> cmds,
                             List<Node> newNodes)

dupe the given node of the given way assume that originalNode is in the way

• the new node will be put into the parameter newNodes.
• the add-node command will be put into the parameter cmds.
• the changed way will be returned and must be put into cmds by the caller!

Parameters:

originalNode - original node to duplicate

w - parent way

cmds - List of commands that will contain the new "add node" command

newNodes - List of nodes that will contain the new node

Returns:

new way The modified way. Change command mus be handled by the caller

fixRelations

private static void fixRelations(Node originalNode,
                                 Collection<Command> cmds,
                                 List<Node> newNodes,
                                 boolean removeOldMember)

put all newNodes into the same relation(s) that originalNode is in

Parameters:

originalNode - original node to duplicate

cmds - List of commands that will contain the new "change relation" commands

newNodes - List of nodes that contain the new node

removeOldMember - whether the membership of the "old node" should be removed

unglueWays

private void unglueWays()

dupe a single node into as many nodes as there are ways using it, OR dupe a single node once, and put the copy on the selected way

execCommands

private static void execCommands(List<Command> cmds,
                                 List<Node> newNodes)

Add commands to undo-redo system.

Parameters:

cmds - Commands to execute

newNodes - New created nodes by this set of command

unglueSelfCrossingWay

private boolean unglueSelfCrossingWay()

Duplicates a node used several times by the same way. See #9896.

Returns:

true if action is OK false if there is nothing to do

unglueOneWayAnyNodes

private void unglueOneWayAnyNodes()

dupe all nodes that are selected, and put the copies on the selected way

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(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
