Constructor Detail

Graph2DViewActions.CloseGroupsAction

public Graph2DViewActions.CloseGroupsAction()

Creates a new CloseGroupAction that has no default view. Invoking this constructor is equivalent to:

new CloseGroupAction(null)

Graph2DViewActions.CloseGroupsAction

public Graph2DViewActions.CloseGroupsAction(Graph2DView view)

Creates a new CloseGroupAction

Parameters:

view - the default view that is used if the actual view cannot be determined from the information provided by an ActionEvent.

Method Detail

isRecursiveClosingEnabled

public boolean isRecursiveClosingEnabled()

Returns whether group nodes that are nested and accepted by acceptNode(Graph2D,y.base.Node) will be closed recursively.

If set to false, only the outermost accepted node in such a nesting will be closed.

Default value is false

Returns:

true if group nodes should be closed recursively.

See Also:

setRecursiveClosingEnabled(boolean)

setRecursiveClosingEnabled

public void setRecursiveClosingEnabled(boolean recursiveClosingEnabled)

Sets whether group nodes that are nested and accepted by acceptNode(Graph2D,y.base.Node) will be closed recursively.

If set to false, only the outermost accepted node in such a nesting will be closed.

Default value is false

Parameters:

recursiveClosingEnabled - true if group nodes should be closed recursively.

See Also:

isRecursiveClosingEnabled()

actionPerformed

public void actionPerformed(ActionEvent e)

closeGroups

public void closeGroups(Graph2DView view)

Close all nodes for which acceptNode(Graph2D,y.base.Node) returns true.

Parameters:

view - The view where all information is used from.

acceptNode

protected boolean acceptNode(Graph2D graph,
                             Node groupNode)

Check whether a node should be changed by this action. This method should return true iff groupNode should be closed.

Returns:

true iff groupNode should be closed.

closeGroup

public void closeGroup(Node groupNode,
                       Graph2D graph)

Closes a single group node. This method closes the node unconditionally. In addition, if Graph2DViewActions.AbstractGroupingAction.getNodeStateChangeHandler() is not null, it is used to configure the relevant edges after closing the node.

configureFolderRealizer

protected void configureFolderRealizer(NodeRealizer realizer)

Updates the group/folder state of the specified realizer if necessary.
