Interface CosNaming::NamingContext

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.

Exceptions

• AlreadyBound

  Indicates an object is already bound to the specified name. Only one object can be bound to a particular name in a context.

      exception AlreadyBound
      {
      };
  

• 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.

      exception CannotProceed
      {
          CosNaming::NamingContext cxt;
          CosNaming::Name rest_of_name;
      };
  

• InvalidName

  Indicates the name is invalid.

      exception InvalidName
      {
      };
  

• NotEmpty

  Indicates that the Naming Context contains bindings.

      exception NotEmpty
      {
      };
  

• NotFound

  Indicates the name does not identify a binding.

      exception NotFound
      {
          CosNaming::NamingContext::NotFoundReason why;
          CosNaming::Name rest_of_name;
      };
  

Operations

• bind

  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. @param n Name of the object

      void bind
      (
          in CosNaming::Name n,
          in Object obj
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName, CosNaming::NamingContext::AlreadyBound);
  

  @param obj The Object to bind with the given name

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

  @exception org.omg.CosNaming.NamingContextPackage.AlreadyBound Indicates an object is already bound to the specified name.

• bind_context

  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. @param n Name of the object

      void bind_context
      (
          in CosNaming::Name n,
          in CosNaming::NamingContext nc
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName, CosNaming::NamingContext::AlreadyBound);
  

  @param nc NamingContect object to bind with the given name

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

  @exception org.omg.CosNaming.NamingContextPackage.AlreadyBound Indicates an object is already bound to the specified name.

• bind_new_context

  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). @param n Name of the object

      CosNaming::NamingContext bind_new_context
      (
          in CosNaming::Name n
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::AlreadyBound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName);
  

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.AlreadyBound Indicates an object is already bound to the specified name.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

• list

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

      void list
      (
          in unsigned long how_many,
          out CosNaming::BindingList bl,
          out CosNaming::BindingIterator bi
      );
  

  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.
  @param how_many the maximum number of bindings to return

  @param bl the returned list of bindings

  @param bi the returned binding iterator

• 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.

      CosNaming::NamingContext new_context
      (
      );
  

• rebind

  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. @param n Name of the object

      void rebind
      (
          in CosNaming::Name n,
          in Object obj
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName);
  

  @parm obj The Object to rebind with the given name

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

• rebind_context

  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. @param n Name of the object

      void rebind_context
      (
          in CosNaming::Name n,
          in CosNaming::NamingContext nc
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName);
  

  @param nc NamingContect object to rebind with the given name

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

• resolve

  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. @param n Name of the object

      Object resolve
      (
          in CosNaming::Name n
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName);
  

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.

• unbind

  The unbind operation removes a name binding from a context. @param n Name of the object

      void unbind
      (
          in CosNaming::Name n
      )
      raises (CosNaming::NamingContext::NotFound, CosNaming::NamingContext::CannotProceed, CosNaming::NamingContext::InvalidName);
  

  @exception org.omg.CosNaming.NamingContextPackage.NotFound Indicates the name does not identify a binding.

  @exception org.omg.CosNaming.NamingContextPackage.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.

  @exception org.omg.CosNaming.NamingContextPackage.InvalidName Indicates that the name is invalid.
