Constructor Detail

NullSceneGraphObjectState

public NullSceneGraphObjectState(SymbolTableData symbol,
                                 Controller control)
Dummy class to represent a null object in the scene graph

Method Detail

writeObject

public void writeObject(java.io.DataOutput out)
                 throws java.io.IOException
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 SceneGraphObjectState
Throws:
java.io.IOException

readObject

public void readObject(java.io.DataInput in)
                throws java.io.IOException
Overrides:
readObject in class SceneGraphObjectState
Throws:
java.io.IOException

getNode

public SceneGraphObject getNode()
Overrides:
getNode in class SceneGraphObjectState

getNodeID

public int getNodeID()
Overrides:
getNodeID in class SceneGraphObjectState

getSymbol

public SymbolTableData getSymbol()
Overrides:
getSymbol 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
