void CosNaming::NamingContext::bind	(	in Name	n,
		in Object	obj
	)			raises (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. A bind operation that is passed a compound name is defined as follows:

 ctx->bind(< c1 ; c2 ; ... ; cn >, obj) :=
 (ctx->resolve(< c1 ; c2 ; ... ; cn-1 >))->bind(< cn >, obj)
 

n - binding name. obj - object to bind. AlreadyBound - if the name is bound in the context.

void CosNaming::NamingContext::bind_context	(	in Name	n,
		in NamingContext	nc
	)			raises (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. A bind_context operation that is passed a compound name is defined as follows:

 ctx->bind_context(< c1 ; c2 ; ... ; cn >, nc) :=
 (ctx->resolve(< c1 ; c2 ; ... ; cn-1 >))->bind_context(< cn >, nc)
 

n - binding name. nc - naming context to bind. AlreadyBound - if the name is bound in the context.

NamingContext CosNaming::NamingContext::bind_new_context

(

in Name

n

)

raises (NotFound, CannotProceed, InvalidName, AlreadyBound)

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). A bind_new_context that is passed a compound name is defined as follows:

 ctx->bind_new_context(< c1 ; c2 ; ... ; cn >) :=
 (ctx->resolve(< c1 ; c2 ; ... ; cn-1 >))->bind_new_context(< cn >)
 

n - binding name.

Returns:

new binding context. AlreadyBound - if the name is bound in the context.

void CosNaming::NamingContext::destroy

(

)

raises (NotEmpty)

The destroy operation deletes a naming context.

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

NotEmpty - if the naming context contains bindings.

void CosNaming::NamingContext::list	(	in unsigned long	how_many,
		out BindingList	bl,
		out 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.

how_many - maximum number of binding to return in bl. bl - list of bindings. bi - iterator over remaining bindings.

NamingContext 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:

new binding context.

void CosNaming::NamingContext::rebind	(	in Name	n,
		in Object	obj
	)			raises (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.

n - binding name. obj - object to bind.

void CosNaming::NamingContext::rebind_context	(	in Name	n,
		in NamingContext	nc
	)			raises (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.

n - binding name. nc - naming context to bind.

Object CosNaming::NamingContext::resolve

(

in Name

n

)

raises (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. Names can have multiple components; therefore, name resolution can traverse multiple contexts. A compound resolve is defined as follows:

 ctx->resolve(< c1 ; c2 ; ... ; cn >) :=
 ctx->resolve(< c1 ; c2 ; ... ; cn-1 >)->resolve(< cn >)
 

n - binding name.

Returns:

bound object.

void CosNaming::NamingContext::unbind

(

in Name

n

)

raises (NotFound, CannotProceed, InvalidName)

The unbind operation removes a name binding from a context.

A unbind operation that is passed a compound name is defined as follows:

 ctx->unbind(< c1 ; c2 ; ... ; cn >) :=
 (ctx->resolve(< c1 ; c2 ; ... ; cn-1 >))->unbind(< cn >)
 

n - binding name.
