list

public javax.naming.NamingEnumeration list(javax.naming.Name name)

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.

                                    throws javax.naming.NamingException

Enumerates the names bound in the named context, along with the class names of objects bound to them.

Specified by:

list in interface javax.naming.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.

public javax.naming.NamingEnumeration listBindings(javax.naming.Name name)
                                            throws javax.naming.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 javax.naming.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:

javax.naming.NamingException - if a naming exception is encountered

destroySubcontext

public void destroySubcontext(javax.naming.Name name)
                       throws javax.naming.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 javax.naming.Context

Parameters:

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

Throws:

javax.naming.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

javax.naming.NamingException

destroySubcontext

public void destroySubcontext(java.lang.String name)
                       throws javax.naming.NamingException

Destroys the named context and removes it from the namespace.

Specified by:

destroySubcontext in interface javax.naming.Context

Parameters:

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

Throws:

javax.naming.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

javax.naming.NamingException

createSubcontext

public javax.naming.Context createSubcontext(javax.naming.Name name)
                                      throws javax.naming.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.

Throws:

Returns:

the object bound to name, not following the terminal link (if any).

Throws:

javax.naming.NamingException - if a naming exception is encountered

public java.lang.Object lookupLink(java.lang.String name)
                            throws javax.naming.NamingException

                                      throws javax.naming.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 javax.naming.Context

Parameters:

Returns:

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

Throws:

javax.naming.NamingException - if a naming exception is encountered

                                      throws javax.naming.NamingException

Retrieves the parser associated with the named context.

Specified by:

getNameParser in interface javax.naming.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:

javax.naming.NamingException - if a naming exception is encountered

                                     javax.naming.Name prefix)
                              throws javax.naming.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 javax.naming.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

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

Specified by:

composeName in interface javax.naming.Context

Parameters:

name - a name relative to this context

prefix - the name of this context relative to one of its ancestors

Returns:

                                   throws javax.naming.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 javax.naming.Context

Returns:

the environment of this context; never null

Throws:

javax.naming.NamingException - if a naming exception is encountered

close

public void close()
           throws javax.naming.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 javax.naming.Context

Throws:

javax.naming.NamingException - if a naming exception is encountered

getNameInNamespace

public java.lang.String getNameInNamespace()
                                    throws javax.naming.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 javax.naming.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

javax.naming.NamingException - if a naming exception is encountered

Specified by:

bind in interface javax.naming.directory.DirContext

Parameters:

name - the name to bind; may not be empty

obj - the object to bind; possibly null
