Proxy Directory Context implementation.
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.
propName
- the name of the environment property to add; may not
be nullpropVal
- the value of the property to add; may not be null
bind
public void bind(Name name,
Object obj)
throws NamingException
Binds a name to an object. All intermediate contexts and the target
context (that named by all but terminal atomic component of the name)
must already exist.
name
- the name to bind; may not be emptyobj
- the object to bind; possibly null
bind
public void bind(Name name,
Object obj,
Attributes attrs)
throws NamingException
Binds a name to an object, along with associated attributes. If attrs
is null, the resulting binding will have the attributes associated
with obj if obj is a DirContext, and no attributes otherwise. If attrs
is non-null, the resulting binding will have attrs as its attributes;
any attributes associated with obj are ignored.
name
- the name to bind; may not be emptyobj
- the object to bind; possibly nullattrs
- the attributes to associate with the binding
bind
public void bind(String name,
Object obj)
throws NamingException

cacheLoad
protected void cacheLoad(CacheEntry entry)
Load entry into cache.
cacheLookup
protected CacheEntry cacheLookup(String name)
throws NamingException
Lookup in cache.
cacheUnload
protected boolean cacheUnload(String name)
Remove entry from cache.
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.
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.
name
- a name relative to this contextprefix
- the name of this context relative to one of its ancestors
- the composition of prefix and name
composeName
public String composeName(String name,
String prefix)
throws NamingException
Composes the name of this context with a name relative to this context.
name
- a name relative to this contextprefix
- the name of this context relative to one of its ancestors
- the composition of prefix and name
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.
name
- the name of the context to create; may not be empty
- the newly created context
createSubcontext
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().
name
- the name of the context to create; may not be emptyattrs
- the attributes to associate with the newly created context
- the newly created context
createSubcontext
public Context createSubcontext(String name)
throws NamingException
Creates and binds a new context.
name
- the name of the context to create; may not be empty
- the newly created context

public DirContext createSubcontext(String name,
Attributes attrs)
throws NamingException
Creates and binds a new context, along with associated attributes.
name
- the name of the context to create; may not be emptyattrs
- the attributes to associate with the newly created context
- the newly created context
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.
name
- the name of the context to be destroyed; may not be empty
destroySubcontext
public void destroySubcontext(String name)
throws NamingException
Destroys the named context and removes it from the namespace.
name
- the name of the context to be destroyed; may not be empty

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().
- the environment of this context; never null
getHostName
public String getHostName()
Return the host name.
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.
- this context's name in its own namespace; never null
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).
name
- the name of the context from which to get the parser

throws NamingException
Binds a name to an object, overwriting any existing binding. All
intermediate contexts and the target context (that named by all but
terminal atomic component of the name) must already exist.
If the object is a DirContext, any existing attributes associated with
the name are replaced with those of the object. Otherwise, any
existing attributes associated with the name remain unchanged.

rebind
public void rebind(Name name,
Object obj,
Attributes attrs)
throws NamingException
Binds a name to an object, along with associated attributes,
overwriting any existing binding. If attrs is null and obj is a
DirContext, the attributes from obj are used. If attrs is null and obj
is not a DirContext, any existing attributes associated with the object
already bound in the directory remain unchanged. If attrs is non-null,
any existing attributes associated with the object already bound in
the directory are removed and attrs is associated with the named
