                                                    Graph2DView view)

Method Detail

getNodeStateChangeHandler

public NodeStateChangeHandler getNodeStateChangeHandler()

Returns a NodeStateChangeHandler instance that will convert the edge state over the grouping operation.

Returns:

The NodeStateChangeHandler instance that will convert the edge state over the grouping operation.

setNodeStateChangeHandler

public void setNodeStateChangeHandler(NodeStateChangeHandler nodeStateChangeHandler)

Sets the NodeStateChangeHandler instance that will convert the edge state over the grouping operation.

Parameters:

nodeStateChangeHandler - The NodeStateChangeHandler instance that will convert the edge state over the grouping operation.

getHierarchyManager

protected HierarchyManager getHierarchyManager(Graph2D graph)

Return the hierarchy manager to use.

Parameters:

graph -

Returns:

A hierarchy manager instance suitable for this action.

getView

protected Graph2DView getView(java.awt.event.ActionEvent e)

Determines the view in which to change graph elements.

Parameters:

e - the ActionEvent that triggers the deletion of graph elements.

Returns:

the view in which to change graph elements.

isReselectNodes

public boolean isReselectNodes()

Return whether previously selected group nodes should stay selected after closing them.

Default value is true.

Returns:

true iff previously selected group nodes should stay selected

setReselectNodes

public void setReselectNodes(boolean reselectNodes)

Set whether previously selected group nodes should stay selected after closing them.

Default value is true.

Parameters:

reselectNodes - true iff previously selected group nodes should stay selected

preNodeStateChange

protected void preNodeStateChange(Node groupNode,
                                  Graph2D g)

Performs necessary actions immediately before the node is closed.

This method delegates to getNodeStateChangeHandler() if one is present. It is called before the actual hierarchy operation is performed.

postNodeStateChange

protected void postNodeStateChange(Node groupNode,
                                   Graph2D g)

Performs necessary actions immediately after the node has been closed.

This method delegates to getNodeStateChangeHandler() if one is present. It is called after the actual hierarchy operation is performed.
