public class ZNameGroup

extends ZGroup

implements ZSerializable, java.io.Serializable

ZNameGroup is a group node that names a portion of the scenegraph. A name group node can be inserted into the tree when an application wants to assign a name to that section of the scenegraph. A static method ZNameGroup.getNameGroup(String name) returns the name group node associated with the specified name.

ZSceneGraphEditor provides a convenience mechanism to locate, create and manage nodes of this type.

Warning: Serialized and ZSerialized objects of this class will not be compatible with future Jazz releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Jazz. A future release of Jazz will provide support for long term persistence.

writeObject

public void writeObject(ZObjectOutputStream out)
                 throws java.io.IOException

Write out all of this object's state.

Specified by:

writeObject in interface ZSerializable

Overrides:

writeObject in class ZGroup

Parameters:

out - The stream that this object writes into

java.io.IOException

writeObjectRecurse

public void writeObjectRecurse(ZObjectOutputStream out)
                        throws java.io.IOException

Specify which objects this object references in order to write out the scenegraph properly

Specified by:

writeObjectRecurse in interface ZSerializable

Overrides:

writeObjectRecurse in class ZGroup

Parameters:

out - The stream that this object writes into

java.io.IOException

setState

public void setState(java.lang.String fieldType,
                     java.lang.String fieldName,
                     java.lang.Object fieldValue)

Set some state of this object as it gets read back in. After the object is created with its default no-arg constructor, this method will be called on the object once for each bit of state that was written out through calls to ZObjectOutputStream.writeState() within the writeObject method.

Specified by:

setState in interface ZSerializable

Overrides:

setState in class ZGroup

Parameters:

fieldType - The fully qualified type of the field

fieldName - The name of the field
