NamingContextOperations

public interface NamingContextOperations
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.

Fields Summary
Constructors Summary
Methods Summary
public voidbind(org.omg.CosNaming.NameComponent[] n, org.omg.CORBA.Object obj)
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

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.

public voidbind_context(org.omg.CosNaming.NameComponent[] n, org.omg.CosNaming.NamingContext nc)
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

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.

public org.omg.CosNaming.NamingContextbind_new_context(org.omg.CosNaming.NameComponent[] n)
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

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.

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

exception
org.omg.CosNaming.NamingContextPackage.NotEmpty Indicates that the Naming Context contains bindings.

public voidlist(int how_many, org.omg.CosNaming.BindingListHolder bl, org.omg.CosNaming.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.

param
how_many the maximum number of bindings to return

param
bl the returned list of bindings

param
bi the returned binding iterator

public org.omg.CosNaming.NamingContextnew_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.

public voidrebind(org.omg.CosNaming.NameComponent[] n, org.omg.CORBA.Object obj)
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

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.

public voidrebind_context(org.omg.CosNaming.NameComponent[] n, org.omg.CosNaming.NamingContext nc)
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

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.

public org.omg.CORBA.Objectresolve(org.omg.CosNaming.NameComponent[] n)
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

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.

public voidunbind(org.omg.CosNaming.NameComponent[] n)
The unbind operation removes a name binding from a context.

param
n Name of the object

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.
