All Implemented Interfaces:

Cloneable, Serializable

public class ModelGraph

extends Group

implements Serializable, Cloneable

This class represents a ModelGraph. A ModelGraph is the root node of the model tree. It includes the focus and the WireBoxGroup. The focus is a link to a node which is focused. It can be null. The WireBoxGroup stores the bounding box shape of the focused object. Title : Earth Copyright : Copyright (c) 2001 Organisation : IGD FhG

Constructor Detail

ModelGraph

public ModelGraph()

Creates an instance of this class.

Method Detail

getType

public int getType()

Returns TYPE_Group. Defined in ModelGraphObject

Overrides:

getType in class Group

Returns:

type (always TYPE_Group)

getSubType

public int getSubType()

Returns SUBTYPE_ModelGraph. Defined in ModelGraphObject

Overrides:

getSubType in class Group

Returns:

subType (always SUBTYPE_ModelGraph)

setFocus

public void setFocus(Node node)

Sets the focus to a given node

Parameters:

node - Node to be focused

getFocus

public Node getFocus()

Returns the focus node.

Returns:

Focus node

update

public void update()

Updates all mutable parts of this class

updateFocus

private void updateFocus()
