Java Enterprise in a Nutshell, Second Edition

Name

Context

Synopsis

This interface represents an object in a naming system. A Context keeps track of a set of name-to-object bindings for its subordinates in the naming system, so it defines methods to examine and update these bindings. The lookup() method looks up a subordinate object, while list() and listBindings() provide access to all of the subordinates.

A Context only knows about its subordinates, not about itself or what is above it in the naming system. Thus, there are no methods to get the name of a Context or move up in the naming hierarchy.
