Examples of org.codehaus.activemq.jndi.ReadOnlyContext$ListBindingEnumeration

org.codehaus.activemq.jndi.ReadOnlyContext
A read-only Context
This version assumes it and all its subcontext are read-only and any attempt to modify (e.g. through bind) will result in an OperationNotSupportedException. Each Context in the tree builds a cache of the entries in all sub-contexts to optimise the performance of lookup.

This implementation is intended to optimise the performance of lookup(String) to about the level of a HashMap get. It has been observed that the scheme resolution phase performed by the JVM takes considerably longer, so for optimum performance lookups should be coded like:
Context componentContext = (Context)new InitialContext().lookup("java:comp"); String envEntry = (String) componentContext.lookup("env/myEntry"); String envEntry2 = (String) componentContext.lookup("env/myEntry2"); @version $Revision: 1.1 $ $Date: 2004/10/12 22:07:40 $

        Map data = new ConcurrentHashMap();
        for (Iterator iter = containerManagerMap.entrySet().iterator(); iter.hasNext();) {
            Map.Entry entry = (Map.Entry) iter.next();
            String name = entry.getKey().toString();
            MessageContainerManager manager = (MessageContainerManager) entry.getValue();
            Context context = new ReadOnlyContext(environment, manager.getDestinations());
            data.put(name, context);
        }
        return new ReadOnlyContext(environment, data);
    }
