org.media.naming
Class MemoryContextFactory  

java.lang.Object
  org.media.naming.MemoryContextFactory

All Implemented Interfaces:

javax.naming.spi.InitialContextFactory

---

public final class MemoryContextFactory

extends java.lang.Object

implements javax.naming.spi.InitialContextFactory

Implements a context factory for MemoryContext. When set properly javax.naming.InitialContext will return a MemoryContext referencing the named path in the shared memory space.

To use this context factory the JNDI properties file must include the following properties:

 java.naming.factory.initial=org.media.naming.MemoryContextFactory
 java.naming.provider.url=
 

Any non-empty URL will return a context to that path in the object tree, relative to the same shared root. The returned context is read/write.

This class was inspired by the tyrex.naming package from the Tyrex project. All credits for the good stuff should go to Assaf Arkin and the Exolab group, all the bad stuff blame it on me :).
