Class JavaNamingImpl

  org.castor.xml.JavaNamingImpl

All Implemented Interfaces:

JavaNaming

public class JavaNamingImpl
extends Object
implements JavaNaming

This class converts XML Names to proper Java names. As Java names are not completely defined this implementation is Castor specific. The first implementation was done by Keith Visco but had been changed radically since.
