• 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

  NamingException

• destroySubcontext

  public void destroySubcontext(String name)
                         throws NamingException

  Destroys the named context and removes it from the namespace.

  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

  NamingException

• 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:

  Returns:

  a name parser that can parse compound names into their atomic components

  Throws:

                 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.

  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

• composeName

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

  Composes the name of this context with a name relative to this context.

  Specified by:

  composeName in interface Context

  NamingException - if a naming exception is encountered

• 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().

  getEnvironment in interface Context

  Returns:

  the environment of this context; never null

  Throws:

  NamingException - if a naming exception is encountered

• 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

  public DirContext createSubcontext(Name name,
                            Attributes attrs)
                              throws NamingException

  Creates and binds a new context, along with associated attributes. This method creates a new subcontext with the given name, binds it in the target context (that named by all but terminal atomic component of the name), and associates the supplied attributes with the newly created object. All intermediate and target contexts must already exist. If attrs is null, this method is equivalent to Context.createSubcontext().

  Specified by:

  createSubcontext in interface DirContext

  Parameters:

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

  attrs - the attributes to associate with the newly created context

  Returns:

  the newly created context

  Throws:

  NameAlreadyBoundException - if name is already bound

  InvalidAttributesException - if attrs does not contain all the mandatory attributes required for creation

  NamingException - if a naming exception is encountered
