Class NamingContextPOATie

All Implemented Interfaces:
InvokeHandler, NamingContextOperations

public class NamingContextPOATie extends NamingContextPOA
A naming context is an object that contains a set of name bindings in which each name is unique. Different names can be bound to an object in the same or different contexts at the same time.

See CORBA COS Naming Specification.

      _default_POA in class Servant
      Returns:
      default_POA the POA associated with the Servant.
    • 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.
      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.
      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.
      Parameters:
      n - Name of the object

      obj - The 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.
    • 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.
      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.
      Parameters:
      n - Name of the object

      Returns:
      the retrieved 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.
      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.
      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.
      Returns:
      the new NamingContext
    • 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).
      Parameters:
      n - Name of the object
      Returns:
      the new NamingContext
      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.
      Throws:
      NotEmpty - Indicates that the Naming Context contains bindings.
