                       throws Exception

Create a top-level naming context.

Parameters:

orb - The orb hosting this context.

poa - The POA used to activate the object.

Throws:

Exception

TransientNamingContext

public TransientNamingContext(ORB orb,
                              POA poa,
                              Object root)
                       throws Exception

Parameters:

orb - The orb this context is associated with.

poa - The POA the root context is activated under.

root - The root context.

Throws:

Exception

Method Detail

new_context

public NamingContext new_context()
                          throws SystemException

Create a new context of the same type as the calling context.

Specified by:

new_context in interface NamingContextOperations

Specified by:

new_context in class NamingContextBase

Returns:

A new NamingContext item.

Throws:

NotFound

SystemException

destroy

public void destroy()
             throws NotEmpty

Destroy a context. This method should clean up any backing resources associated with the context.

Specified by:

destroy in interface NamingContextOperations

Specified by:

destroy in class NamingContextBase

Throws:

NotEmpty

list

public void list(int how_many,
                 BindingListHolder bl,
                 BindingIteratorHolder bi)
          throws SystemException

Create a list of bound objects an contexts contained within this context.

Specified by:

list in interface NamingContextOperations

Specified by:

list in class NamingContextBase

Parameters:

how_many - The count of elements to return as a BindingList.

bl - A holder element for returning the source binding list.

bi - A holder for returning a BindingIterator. Any extra elements not returned in the BindingList are returned in the BindingIterator.

Throws:

SystemException

Specified by:

resolveObject in class NamingContextBase

Parameters:

n - The name of the target object.

type - A type holder for returning the bound object type information.

Returns:

The bound object. Returns null if the object does not exist in the context.
