Method Detail

bind

public void bind(org.omg.CosNaming.NameComponent[] n,
                 org.omg.CORBA.Object obj)
          throws org.omg.CosNaming.NamingContextPackage.NotFound,
                 org.omg.CosNaming.NamingContextPackage.CannotProceed,
                 org.omg.CosNaming.NamingContextPackage.InvalidName,
                 org.omg.CosNaming.NamingContextPackage.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 - The compound name for the object to bind
obj - The object to bind
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.
org.omg.CosNaming.NamingContextPackage.InvalidName - Indicates the name is invalid. (A name of length 0 is invalid; implementations may place other restrictions on names.)
org.omg.CosNaming.NamingContextPackage.AlreadyBound - Indicates an object is already bound to the specified name. Only one object can be bound to a particular name in a context. The bind and the bind_context operations raise the AlreadyBound exception if the name is bound in the context; the rebind and rebind_context operations unbind the name and rebind the name to the object passed as an argument.

rebind

public void rebind(org.omg.CosNaming.NameComponent[] n,
                   org.omg.CORBA.Object obj)
            throws org.omg.CosNaming.NamingContextPackage.NotFound,
                   org.omg.CosNaming.NamingContextPackage.CannotProceed,
                   org.omg.CosNaming.NamingContextPackage.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 - The compound name for the object to rebind
obj - The object to rebind
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.
org.omg.CosNaming.NamingContextPackage.InvalidName - Indicates the name is invalid. (A name of length 0 is invalid; implementations may place other restrictions on names.)

bind_context

public void bind_context(org.omg.CosNaming.NameComponent[] n,
                         org.omg.CosNaming.NamingContext nc)
                  throws org.omg.CosNaming.NamingContextPackage.NotFound,
                         org.omg.CosNaming.NamingContextPackage.CannotProceed,
                         org.omg.CosNaming.NamingContextPackage.InvalidName,
                         org.omg.CosNaming.NamingContextPackage.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 - The compound name for the naming context to bind
nc - The naming context to bind
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.
org.omg.CosNaming.NamingContextPackage.InvalidName - Indicates the name is invalid. (A name of length 0 is invalid; implementations may place other restrictions on names.)
org.omg.CosNaming.NamingContextPackage.AlreadyBound - Indicates an object is already bound to the specified name. Only one object can be bound to a particular name in a context. The bind and the bind_context operations raise the AlreadyBound exception if the name is bound in the context; the rebind and rebind_context operations unbind the name and rebind the name to the object passed as an argument.

rebind_context

public void rebind_context(org.omg.CosNaming.NameComponent[] n,
                           org.omg.CosNaming.NamingContext nc)
                    throws org.omg.CosNaming.NamingContextPackage.NotFound,
                           org.omg.CosNaming.NamingContextPackage.CannotProceed,
                           org.omg.CosNaming.NamingContextPackage.InvalidName

Parameters:
n - The compound name for the naming context to rebind
nc - The naming context to rebind
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.
org.omg.CosNaming.NamingContextPackage.InvalidName - Indicates the name is invalid. (A name of length 0 is invalid; implementations may place other restrictions on names.)

                   org.omg.CosNaming.NamingContextPackage.InvalidName
The unbind operation removes a name binding from a context.

Parameters:
n - The compound name for the node to unbind ( an object or a naming context )
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.

new_context

public org.omg.CosNaming.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:
A new naming context ( this new naming context must be binded )

bind_new_context

public org.omg.CosNaming.NamingContext bind_new_context(org.omg.CosNaming.NameComponent[] n)
                                                 throws org.omg.CosNaming.NamingContextPackage.NotFound,
                                                        org.omg.CosNaming.NamingContextPackage.AlreadyBound,

                                                        org.omg.CosNaming.NamingContextPackage.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 - The compound name for the naming context to create and to bind.
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.

org.omg.CosNaming.NamingContextPackage.AlreadyBound - Indicates an object is already bound to the specified name. Only one object can be bound to a particular name in a context.

destroy

public void destroy()
             throws org.omg.CosNaming.NamingContextPackage.NotEmpty
The destroy operation deletes a naming context.

Throws:
org.omg.CosNaming.NamingContextPackage.NotEmpty - If the naming context contains bindings, the NotEmpty exception is raised.

list

public void list(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.

Parameters:
how_many - Maximum number of elements into the binding list.
bl - This parameter returns a list that contains all node of the naming context
bi - This parameter returns a binding iterator to iterate in the list.

to_string

public java.lang.String to_string(org.omg.CosNaming.NameComponent[] n)
                           throws org.omg.CosNaming.NamingContextPackage.InvalidName
This operation accepts Name and returns a stringified name.

Parameters:
n - the name to stringified.
Throws:
org.omg.CosNaming.NamingContextPackage.InvalidName - This exception is raised if the name is invalid.

to_name

public org.omg.CosNaming.NameComponent[] to_name(java.lang.String sn)
                                          throws org.omg.CosNaming.NamingContextPackage.InvalidName
This operation accepts a stringified name and returns a Name.

Parameters:
sn - the stringified name to transform to a name.
Throws:
org.omg.CosNaming.NamingContextPackage.InvalidName - This exception is raised if the stringified name is syntactically malformed or violates an implementation limit.

to_url

public java.lang.String to_url(java.lang.String addr,
                               java.lang.String sn)
                        throws org.omg.CosNaming.NamingContextExtPackage.InvalidAddress,
                               org.omg.CosNaming.NamingContextPackage.InvalidName
This operation takes an URL address and performs any escapes necessary on the stringified name and returns a fully formed URL string.

Parameters:
addr - the address ( for example myhost.xyz.com )
sn - the stringified name to add to the URL
Returns:
the URL string format.
Throws:
org.omg.CosNaming.NamingContextExtPackage.InvalidAddress - This exception is raises if a address is invalid ( it means that the address does not respect the address format ).
org.omg.CosNaming.NamingContextPackage.InvalidName - This exception is raised if the stringified name is syntactically malformed or violates an implementation limit.

resolve_str

public org.omg.CORBA.Object resolve_str(java.lang.String n)
                                 throws org.omg.CosNaming.NamingContextPackage.NotFound,
                                        org.omg.CosNaming.NamingContextPackage.CannotProceed,
                                        org.omg.CosNaming.NamingContextPackage.InvalidName
This is a convenience operation that performs a resolve in the same manner as NamingContext::resolve. It accepts a stringified name as an argument instead of a Name.

Parameters:
n - the stringified name of the object ( or naming context ) to resolve
Returns:
the resolved object.
Throws:
org.omg.CosNaming.NamingContextPackage.NotFound - Indicates the name does not identify a binding.
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.
org.omg.CosNaming.NamingContextPackage.InvalidName - Indicates the name is invalid. (A name of length 0 is invalid; implementations may place other restrictions on names.)
