                   String newName)
            throws NamingException

Binds a new name to the object bound to an old name, and unbinds the old name. See rename(Name, Name) for details.

Specified by:: rename in interface Context

Parameters:: oldName - the name of the existing binding; may not be empty; newName - the name of the new binding; may not be empty
Throws:: NameAlreadyBoundException - if newName is already bound; NamingException - if a naming exception is encountered

list

public NamingEnumeration list(Name name)
                       throws NamingException

Enumerates the names bound in the named context, along with the class names of objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:: list in interface Context

Parameters:: name - the name of the context to list
Returns:: an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.
Throws:: NamingException - if a naming exception is encountered
See Also:: list(String), listBindings(Name), NameClassPair

list

public NamingEnumeration list(String name)
                       throws NamingException

Enumerates the names bound in the named context, along with the class names of objects bound to them. See list(Name) for details.

Specified by:: list in interface Context

Parameters:: name - the name of the context to list
Returns:: an enumeration of the names and class names of the bindings in this context. Each element of the enumeration is of type NameClassPair.
Throws:: NamingException - if a naming exception is encountered

listBindings

public NamingEnumeration listBindings(Name name)
                               throws NamingException

Enumerates the names bound in the named context, along with the objects bound to them. The contents of any subcontexts are not included.

If a binding is added to or removed from this context, its effect on an enumeration previously returned is undefined.

Specified by:: listBindings in interface Context

Parameters:: name - the name of the context to list
Returns:: an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.
Throws:: NamingException - if a naming exception is encountered
See Also:: listBindings(String), list(Name), Binding

listBindings

public NamingEnumeration listBindings(String name)

Parameters:: name - the name of the context to list
Returns:: an enumeration of the bindings in this context. Each element of the enumeration is of type Binding.
Throws:: NamingException - if a naming exception is encountered

destroySubcontext

public void destroySubcontext(Name name)
                       throws NamingException

Destroys the named context and removes it from the namespace. Any attributes associated with the name are also removed. Intermediate contexts are not destroyed.

This method is idempotent. It succeeds even if the terminal atomic name is not bound in the target context, but throws NameNotFoundException if any of the intermediate contexts do not exist.

In a federated naming system, a context from one naming system may be bound to a name in another. One can subsequently look up and perform operations on the foreign context using a composite name. However, an attempt destroy the context using this composite name will fail with NotContextException, because the foreign context is not a "subcontext" of the context in which it is bound. Instead, use unbind() to remove the binding of the foreign context. Destroying the foreign context requires that the destroySubcontext() be performed on a context from the foreign context's "native" naming system.

Specified by:: destroySubcontext in interface Context

Parameters:: name - the name of the context to be destroyed; may not be empty
Throws:: NameNotFoundException - if an intermediate context does not exist; NotContextException - if the name is bound but does not name a context, or does not name a context of the appropriate type; ContextNotEmptyException - if the named context is not empty; NamingException - if a naming exception is encountered
See Also:: destroySubcontext(String)

destroySubcontext

public void destroySubcontext(String name)
                       throws NamingException

Destroys the named context and removes it from the namespace. See destroySubcontext(Name) for details.

Specified by:: destroySubcontext in interface Context

Parameters:: name - the name of the context to be destroyed; may not be empty
Throws:: NameNotFoundException - if an intermediate context does not exist; NotContextException - if the name is bound but does not name a context, or does not name a context of the appropriate type; ContextNotEmptyException - if the named context is not empty; NamingException - if a naming exception is encountered

createSubcontext

public Context createSubcontext(Name name)
                         throws NamingException

Creates and binds a new context. Creates a new context with the given name and binds it in the target context (that named by all but terminal atomic component of the name). All intermediate contexts and the target context must already exist.

Specified by:: createSubcontext in interface Context

Parameters:: name - the name of the context to create; may not be empty
Returns:: the newly created context
Throws:: NameAlreadyBoundException - if name is already bound; InvalidAttributesException - if creation of the subcontext requires specification of mandatory attributes; NamingException - if a naming exception is encountered
See Also:: createSubcontext(String), DirContext.createSubcontext(java.lang.String, javax.naming.directory.Attributes)

createSubcontext

public Context createSubcontext(String name)
                         throws NamingException

Creates and binds a new context. See createSubcontext(Name) for details.

Specified by:: createSubcontext in interface Context

Parameters:: name - the name of the context to create; may not be empty

Throws:: NameAlreadyBoundException - if name is already bound; InvalidAttributesException - if creation of the subcontext requires specification of mandatory attributes; NamingException - if a naming exception is encountered

lookupLink

public Object lookupLink(Name name)
                  throws NamingException

Specified by:: lookupLink in interface Context

Parameters:: name - the name of the object to look up
Returns:: the object bound to name, not following the terminal link (if any).
Throws:: NamingException - if a naming exception is encountered
See Also:: lookupLink(String)

lookupLink

public Object lookupLink(String name)
                  throws NamingException

Retrieves the named object, following links except for the terminal atomic component of the name. See lookupLink(Name) for details.

Specified by:: lookupLink in interface Context

Parameters:: name - the name of the object to look up
Returns:: the object bound to name, not following the terminal link (if any)
Throws:: NamingException - if a naming exception is encountered

getNameParser

public NameParser getNameParser(Name name)
                         throws NamingException

Retrieves the parser associated with the named context. In a federation of namespaces, different naming systems will parse names differently. This method allows an application to get a parser for parsing names into their atomic components using the naming convention of a particular naming system. Within any single naming system, NameParser objects returned by this method must be equal (using the equals() test).

Specified by:: getNameParser in interface Context

Parameters:: name - the name of the context from which to get the parser
Returns:: a name parser that can parse compound names into their atomic components
Throws:: NamingException - if a naming exception is encountered
See Also:: getNameParser(String), CompoundName

getNameParser

public NameParser getNameParser(String name)
                         throws NamingException

Retrieves the parser associated with the named context. See getNameParser(Name) for details.

Specified by:: getNameParser in interface Context

Parameters:: name - the name of the context from which to get the parser
Returns:: a name parser that can parse compound names into their atomic components
Throws:: NamingException - if a naming exception is encountered

composeName

public Name composeName(Name name,
                        Name prefix)
                 throws NamingException

Composes the name of this context with a name relative to this context. Given a name (name) relative to this context, and the name (prefix) of this context relative to one of its ancestors, this method returns the composition of the two names using the syntax appropriate for the naming system(s) involved. That is, if name names an object relative to this context, the result is the name of the same object, but relative to the ancestor context. None of the names may be null.

For example, if this context is named "wiz.com" relative to the initial context, then

 	composeName("east", "wiz.com")

might return "east.wiz.com". If instead this context is named "org/research", then

 	composeName("user/jane", "org/research")

might return "org/research/user/jane" while

 	composeName("user/jane", "research")

returns "research/user/jane".

Specified by:: composeName in interface Context

Parameters:: name - a name relative to this context; prefix - the name of this context relative to one of its ancestors
Returns:: the composition of prefix and name
Throws:: NamingException - if a naming exception is encountered
See Also:: composeName(String, String)

composeName

public String composeName(String name,
                          String prefix)
                   throws NamingException

Composes the name of this context with a name relative to this context. See composeName(Name, Name) for details.

Specified by:: composeName in interface Context

Parameters:: name - a name relative to this context; prefix - the name of this context relative to one of its ancestors
Returns:: the composition of prefix and name
Throws:: NamingException - if a naming exception is encountered

addToEnvironment

public Object addToEnvironment(String propName,
                               Object propVal)
                        throws NamingException

Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten. See class description for more details on environment properties.

Specified by:: addToEnvironment in interface Context

Parameters:: propName - the name of the environment property to add; may not be null; propVal - the value of the property to add; may not be null
Returns:: the previous value of the property, or null if the property was not in the environment before
Throws:: NamingException - if a naming exception is encountered
See Also:: getEnvironment(), removeFromEnvironment(String)

removeFromEnvironment

public Object removeFromEnvironment(String propName)
                             throws NamingException

Removes an environment property from the environment of this context. See class description for more details on environment properties.

Specified by:: removeFromEnvironment in interface Context

Parameters:: propName - the name of the environment property to remove; may not be null
Returns:: the previous value of the property, or null if the property was not in the environment
Throws:: NamingException - if a naming exception is encountered
See Also:: getEnvironment(), addToEnvironment(String, Object)

getEnvironment

public Hashtable getEnvironment()
                         throws NamingException

Retrieves the environment in effect for this context. See class description for more details on environment properties.

The caller should not make any changes to the object returned: their effect on the context is undefined. The environment of this context may be changed using addToEnvironment() and removeFromEnvironment().

Specified by:: getEnvironment in interface Context

Returns:: the environment of this context; never null
Throws:: NamingException - if a naming exception is encountered
See Also:: addToEnvironment(String, Object), removeFromEnvironment(String)

close

public void close()
           throws NamingException

Closes this context. This method releases this context's resources immediately, instead of waiting for them to be released automatically by the garbage collector.

This method is idempotent: invoking it on a context that has already been closed has no effect. Invoking any other method on a closed context is not allowed, and results in undefined behaviour.

Specified by:: close in interface Context

Throws:: NamingException - if a naming exception is encountered

getNameInNamespace

public String getNameInNamespace()
                          throws NamingException

Retrieves the full name of this context within its own namespace.

Many naming services have a notion of a "full name" for objects in their respective namespaces. For example, an LDAP entry has a distinguished name, and a DNS record has a fully qualified name. This method allows the client application to retrieve this name. The string returned by this method is not a JNDI composite name and should not be passed directly to context methods. In naming systems for which the notion of full name does not make sense, OperationNotSupportedException is thrown.

Specified by:: getNameInNamespace in interface Context

Returns:: this context's name in its own namespace; never null
Throws:: OperationNotSupportedException - if the naming system does not have the notion of a full name; NamingException - if a naming exception is encountered
Since:: 1.3
