Field Detail

• groupChildren

  protected SceneGraphObjectState[] groupChildren

Constructor Detail

• GroupState

  public GroupState(SymbolTableData symbol,
                    Controller control)

Method Detail

• writeObject

  public void writeObject(DataOutput out)
                   throws IOException

  Description copied from class: SceneGraphObjectState
  DO NOT call symbolTable.addReference in writeObject as this (may) result in a concurrentModificationException. All references should be created in the constructor

  Overrides:

  writeObject in class NodeState

  Throws:

  IOException

• readObject

  public void readObject(DataInput in)
                  throws IOException

  Overrides:

  readObject in class NodeState

  Throws:

  IOException

• processChildren

  protected boolean processChildren()

  Returns true if the groups children should be saved. This is overridden by 'black box' groups such a geometry primitives When users create nodes that implement SceneGraphIO interface then this method is superceded by saveChildren() in the SceneGraphIO interface

• buildGraph

  public void buildGraph()

  Description copied from class: SceneGraphObjectState
  Subclasses should processes their own buildGraph requirements BEFORE calling super.buildGraph(). This ensures that when restoreSceneGraphObjectReferences is called in user code our references have been resolved

  Overrides:

  buildGraph in class SceneGraphObjectState

• cleanup

  public void cleanup()

  Overrides:

  cleanup in class SceneGraphObjectState

• createNode

  protected SceneGraphObject createNode()

  Description copied from class: SceneGraphObjectState
  Create a new Java3D node for this object. This method is ONLY used when the Java3D Class type matches the State type, ie this does NOT handle subclasses of Java3D. For Java3D subclasses use createNode( Class state) This method MUST be implemented by all State objects but is not abstract to allow for external subclassing

  Overrides:

  createNode in class SceneGraphObjectState
