Naming Operations

Creating and Destroying a Context

The Context interface contains methods for creating and destroying a subcontext. A subcontext is a context that is bound in another context of the same type. In a file system, this corresponds to creating and removing a subdirectory.

Creating a Context

To create a context, you supply the name of the context you want to create to the createSubcontext() method:

// Create the context
Context result = ctx.createSubcontext("new");

This example creates a new context, called "new", that is a child of ctx. If you list the context ctx, you will see that there is now an entry for "new".

Destroying a Context

To destroy a context, you supply the name of the context to destroy to the destroySubcontext() method:

// Destroy the context
ctx.destroySubcontext("new");

This example destroys the context "new" in the context "ctx".
