| AtomicContext | Clients: deal only with names for its own naming service and deals with single contexts that can be built up into hierarchical naming systems. |
| AtomicDirContext | Direct subclasses of AtomicDirContext must provide implementations for the abstract a_ DirContext methods, and override the a_ Context methods (which are no longer abstract because they have been overriden by PartialCompositeDirContext with dummy implementations). |
| ComponentContext | Provides implementation of p_* operations using c_* operations provided by subclasses. |
| ComponentDirContext | |
| Continuation | This class contains information required to continue the method (place where it left off, and remaining name to continue). |
| HeadTail | A class for returning the result of p_parseComponent(); |
| PartialCompositeContext | PartialCompositeContext implements Context operations on composite names using implementations of the p_ interfaces defined by its subclasses. |
| PartialCompositeDirContext | |
| StringHeadTail | A class for returning the result of c_parseComponent(). |
