Interface GenericNodeRealizer.UserDataHandler

All Known Implementing Classes:

SimpleUserDataHandler

Enclosing class:

GenericNodeRealizer

public static interface GenericNodeRealizer.UserDataHandler

This interface is used by GenericNodeRealizer to delegate the copying and serialization/deserialization of any user-defined data to. Registered implementations of this interface will be used to perform the actual serialization and deserialization of the user-defined data object. Additionally, implementations are responsible for creating appropriate copies of the user-defined data.

Method Summary

Object	copyUserData(NodeRealizer srcContext, Object srcData, NodeRealizer targetContext) Used as a callback for the GenericNodeRealizer.createCopy(NodeRealizer) method to copy the user data from the original node to the target node.
Object	readUserData(NodeRealizer context, ObjectInputStream ois) Used as a callback for the GenericNodeRealizer.read(java.io.ObjectInputStream) method to read the user data from the stream.
void	storeUserData(NodeRealizer context, Object userData, ObjectOutputStream oos) Used as a callback for the GenericNodeRealizer.write(java.io.ObjectOutputStream) method to store the user data to the stream.
