Method Detail

bind

public void bind(NameComponent[] n,
                 Object obj)
          throws NotFound,
                 CannotProceed,
                 InvalidName,
                 AlreadyBound

Creates a binding of a name and an object in the naming context. Naming contexts that are bound using bind do not participate in name resolution when compound names are passed to be resolved.

Specified by:

bind in interface NamingContextOperations

Parameters:

n - Name of the object

obj - The Object to bind with the given name

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

AlreadyBound - Indicates an object is already bound to the specified name.

bind_context

public void bind_context(NameComponent[] n,
                         NamingContext nc)
                  throws NotFound,
                         CannotProceed,
                         InvalidName,
                         AlreadyBound

Names an object that is a naming context. Naming contexts that are bound using bind_context() participate in name resolution when compound names are passed to be resolved.

Specified by:

bind_context in interface NamingContextOperations

Parameters:

n - Name of the object

nc - NamingContect object to bind with the given name

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

AlreadyBound - Indicates an object is already bound to the specified name.

rebind

public void rebind(NameComponent[] n,
                   Object obj)
            throws NotFound,
                   CannotProceed,
                   InvalidName

Creates a binding of a name and an object in the naming context even if the name is already bound in the context. Naming contexts that are bound using rebind do not participate in name resolution when compound names are passed to be resolved.

Specified by:

rebind in interface NamingContextOperations

Parameters:

n - Name of the object

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

rebind_context

public void rebind_context(NameComponent[] n,
                           NamingContext nc)
                    throws NotFound,
                           CannotProceed,
                           InvalidName

Creates a binding of a name and a naming context in the naming context even if the name is already bound in the context. Naming contexts that are bound using rebind_context() participate in name resolution when compound names are passed to be resolved.

Specified by:

rebind_context in interface NamingContextOperations

Parameters:

n - Name of the object

nc - NamingContect object to rebind with the given name

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

resolve

public Object resolve(NameComponent[] n)
               throws NotFound,
                      CannotProceed,
                      InvalidName

The resolve operation is the process of retrieving an object bound to a name in a given context. The given name must exactly match the bound name. The naming service does not return the type of the object. Clients are responsible for "narrowing" the object to the appropriate type. That is, clients typically cast the returned object from Object to a more specialized interface.

Specified by:

resolve in interface NamingContextOperations

Parameters:

n - Name of the object

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

unbind

public void unbind(NameComponent[] n)
            throws NotFound,
                   CannotProceed,
                   InvalidName

The unbind operation removes a name binding from a context.

Specified by:

unbind in interface NamingContextOperations

Parameters:

n - Name of the object

Throws:

NotFound - Indicates the name does not identify a binding.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

list

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

The list operation allows a client to iterate through a set of bindings in a naming context.

The list operation returns at most the requested number of bindings in BindingList bl.

• If the naming context contains additional bindings, the list operation returns a BindingIterator with the additional bindings.
• If the naming context does not contain additional bindings, the binding iterator is a nil object reference.

Specified by:

list in interface NamingContextOperations

Parameters:

how_many - the maximum number of bindings to return

bl - the returned list of bindings

bi - the returned binding iterator

new_context

public NamingContext new_context()

This operation returns a naming context implemented by the same naming server as the context on which the operation was invoked. The new context is not bound to any name.

Specified by:

new_context in interface NamingContextOperations

bind_new_context

public NamingContext bind_new_context(NameComponent[] n)
                               throws NotFound,
                                      AlreadyBound,
                                      CannotProceed,
                                      InvalidName

This operation creates a new context and binds it to the name supplied as an argument. The newly-created context is implemented by the same naming server as the context in which it was bound (that is, the naming server that implements the context denoted by the name argument excluding the last component).

Specified by:

bind_new_context in interface NamingContextOperations

Parameters:

n - Name of the object

Throws:

NotFound - Indicates the name does not identify a binding.

AlreadyBound - Indicates an object is already bound to the specified name.

CannotProceed - Indicates that the implementation has given up for some reason. The client, however, may be able to continue the operation at the returned naming context.

InvalidName - Indicates that the name is invalid.

destroy

public void destroy()
             throws NotEmpty

The destroy operation deletes a naming context. If the naming context contains bindings, the NotEmpty exception is raised.

Specified by:

destroy in interface NamingContextOperations

Throws:

NotEmpty - Indicates that the Naming Context contains bindings.

_ids

public java.lang.String[] _ids()

Description copied from class: ObjectImpl

Retrieves a string array containing the repository identifiers supported by this ObjectImpl object. For example, for a stub, this method returns information about all the interfaces supported by the stub.

Specified by:

_ids in class ObjectImpl

Returns:

the array of all repository identifiers supported by this ObjectImpl instance
