All Implemented Interfaces:

javax.naming.Context, ContextAncestors, javax.naming.event.EventContext

public class SystemContext

extends AbstractSimpleCtx

The PreferenceCtx is used to supply preferences for application configuration.

This Context has its own bindings and can pass on its lookup requests to other Contexts that have been installed under this one using the addContext() method. When Contexts are installed under this one the subcontexts do not extend the name space.

Method Summary

protected void	bind_internal(javax.naming.Name name, java.lang.Object obj) Put the name in your bindings.
protected javax.naming.Context	cloneCtx()
protected javax.naming.NameParser	getNameParser()
javax.naming.NamingEnumeration	list(javax.naming.Name name)
javax.naming.NamingEnumeration	listBindings(javax.naming.Name name)
protected java.lang.Object	lookup_internal(javax.naming.Name name) Lookup the name in your bindings.
protected java.lang.Object	rebind_internal(javax.naming.Name name, java.lang.Object obj) Rebind a new Object to a name.
protected java.lang.Object	unbind_internal(javax.naming.Name name) The name can not actually be unbound since there is no way to remove a property name so the value is set to an empty String.
