question: protected void a_processJunction_nns ( String name , Continuation cont ) throws NamingException { if ( name . equals ( "" ) ) { NameNotFoundException e = new NameNotFoundException ( ) ; cont . setErrorNNS ( this , name ) ; throw cont . fillInException ( e ) ; } try { Object target = a_lookup ( name , cont ) ; if ( cont . isContinue ( ) ) cont . appendRemainingComponent ( "" ) ; else { cont . setContinueNNS ( target , name , this ) ; } } catch ( NamingException e ) { e . appendRemainingComponent ( "" ) ; throw e ; } }
target:  This function is used when implementing a naming system that supports junctions.  For example, when the a_bind_nns(name, newobj) method is invoked, that means the caller is attempting to bind the object 'newobj' to the nns of 'name'.  For context that supports junctions, 'name' names a junction and is pointing to the root of another naming system, which in turn might have an nns. This means that a_bind_nns() should first resolve 'name' and attempt to continue the operation in the context named by 'name'.  (i.e. bind to the nns of the context named by 'name'). If name is already empty, then throw NameNotFoundException because this context by default does not have any nns.
