Enclosing class:

LocalViewCreator

public static class LocalViewCreator.AncestorGroups
extends LocalViewCreator.AbstractLocalViewCreator

Local view creator that creates local views that display all ancestor group nodes of the creator's focus nodes. An ancestor node of a given node is a group node that either contains the node or one of its ancestor nodes.

This class uses ModelViewManager to actually create graph elements in its associated view graph and manage mappings between elements in its model graph and its view graph.

Constructor Detail

LocalViewCreator.AncestorGroups

public LocalViewCreator.AncestorGroups(Graph2D model)

Creates a new AncestorGroups instance for the specified model graph. Invoking this constructor is equivalent to:

new AncestorGroups(model, model.getGraphCopyFactory(), (Graph2D) model.getGraphCopyFactory().createGraph());

Parameters:

model - the graph for which local views are to be created.

LocalViewCreator.AncestorGroups

public LocalViewCreator.AncestorGroups(Graph2D model,
                                       GraphCopier.CopyFactory factory)

Creates a new AncestorGroups instance for the specified model graph and copy factory. Invoking this constructor is equivalent to:

new AncestorGroups(model, factory, (Graph2D) factory.createGraph());

Note: The graph instances created by the specified factory have to be of type Graph2D or subclasses thereof. Moreover, the factory.

Parameters:

model - the graph for which local views are to be created.

factory - that CopyFactory that will be used to create graph elements in the creator's view graph.

LocalViewCreator.AncestorGroups

public LocalViewCreator.AncestorGroups(Graph2D model,
                                       GraphCopier.CopyFactory factory,
                                       Graph2D view)

Creates a new AncestorGroups instance for the specified model graph, copy factory, and view graph.

Note: The specified factory has to be able to create graph elements in the specified view graph.

Parameters:

model - the graph for which local views are to be created.

factory - that CopyFactory that will be used to create graph elements in the creator's view graph.

view - the graph that will be modified by the creator.

Method Detail

isIncludeFocusNodes

public boolean isIncludeFocusNodes()

Determines whether the creator's focus nodes should be included in the created local view as well.

By default, this property is set to true.

Returns:

true if the creator's focus nodes should be included in the created local view as well and false otherwise.

See Also:

setIncludeFocusNodes(boolean)

setIncludeFocusNodes

public void setIncludeFocusNodes(boolean includeFocusNodes)

Specifies whether the creator's focus nodes should be included in the created local view as well.

By default, this property is set to true.

Parameters:

includeFocusNodes - true if the creator's focus nodes should be included in the created local view as well and false otherwise.
