public class _NamingContextExtStub extends ObjectImpl implements NamingContextExt
NamingContextExt is the extension of NamingContext which contains a set of name bindings in which each name is unique and is part of Interoperable Naming Service. Different names can be bound to an object in the same or different contexts at the same time. Using NamingContextExt, you can use URL-based names to bind and resolve.
public _NamingContextExtStub()
public String to_string(NameComponent[] n)
throws InvalidName This operation creates a stringified name from the array of Name components.
to_string in interface NamingContextExtOperations
n - Name of the object
org.omg.CosNaming.NamingContextExtPackage.InvalidName - Indicates the name does not identify a binding.
InvalidNamepublic NameComponent[] to_name(String sn)
throws InvalidName This operation converts a Stringified Name into an equivalent array of Name Components.
to_name in interface NamingContextExtOperations
sn - Stringified Name of the object
org.omg.CosNaming.NamingContextExtPackage.InvalidName - Indicates the name does not identify a binding.
InvalidNamepublic String to_url(String addr,
String sn)
throws InvalidAddress,
InvalidName This operation creates a URL based "iiopname://" format name from the Stringified Name of the object.
to_url in interface NamingContextExtOperations
addr - internet based address of the host machine where Name Service is running
sn - Stringified Name of the object
org.omg.CosNaming.NamingContextExtPackage.InvalidName - Indicates the name does not identify a binding.
org.omg.CosNaming.NamingContextPackage.InvalidAddress - Indicates the internet based address of the host machine is incorrect
InvalidAddressInvalidNamepublic Object resolve_str(String sn)
throws NotFound,
CannotProceed,
InvalidName This operation resolves the Stringified name into the object reference.
resolve_str in interface NamingContextExtOperations
sn - Stringified Name of the object
NotFound - Indicates there is no object reference for the given name.
CannotProceed - Indicates that the given compound name is incorrect
org.omg.CosNaming.NamingContextExtPackage.InvalidName - Indicates the name does not identify a binding.
InvalidNamepublic 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.
bind in interface NamingContextOperations
n - Name of the object
obj - The Object to bind with the given name
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.
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.
bind_context in interface NamingContextOperations
n - Name of the object
nc - NamingContect object to bind with the given name
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.
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.
rebind in interface NamingContextOperations
n - Name of the object
obj - The Object to rebind with the given name
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.
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.
rebind_context in interface NamingContextOperations
n - Name of the object
nc - NamingContect object to rebind with the given name
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.
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.
resolve in interface NamingContextOperations
n - Name of the object
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.
public void unbind(NameComponent[] n)
throws NotFound,
CannotProceed,
InvalidName The unbind operation removes a name binding from a context.
unbind in interface NamingContextOperations
n - Name of the object
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.
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.
list in interface NamingContextOperations
how_many - the maximum number of bindings to return
bl - the returned list of bindings
bi - the returned binding iterator
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.
new_context in interface NamingContextOperations
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).
bind_new_context in interface NamingContextOperations
n - Name of the object
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.
public void destroy()
throws NotEmpty The destroy operation deletes a naming context. If the naming context contains bindings, the NotEmpty exception is raised.
destroy in interface NamingContextOperations
NotEmpty - Indicates that the Naming Context contains bindings.public 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.
