public interface NamingContext
extends NamingContextOperations, org.omg.CORBA.Object, org.omg.CORBA.portable.IDLEntity

The interface for the naming context. The naming context can store (bound) and retrieve (resolve) the named objects or named child contexts. These operations are defined in a separate interface.

Create a new context and give it a given name (bound it) in the current context.

Specified by:

bind_new_context in interface NamingContextOperations

Parameters:

a_name - the name being given to the new context.

Returns:

the newly created context.

Throws:

org.omg.CosNaming.NamingContextPackage.AlreadyBound - if the name is already in use.

org.omg.CosNaming.NamingContextPackage.InvalidName - if the name has zero length or otherwise invalid.

destroy

void destroy()
             throws org.omg.CosNaming.NamingContextPackage.NotEmpty

Destroy this context (must be empty).

Specified by:

destroy in interface NamingContextOperations

Throws:

        BindingIteratorHolder an_iter)

Iterate over all bindings, defined in this namind context.

Specified by:
