Context implementation for the "scn:comp" namespace.
Package must be named .../scn (See Initial Context)
Most operations consist of retrieving the actual CompNamingContext
and sending it the operation for processing.
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.
propName
- the name of the environment property to add; may not be nullpropVal
- the value of the property to add; may not be null
- the previous value of the property, or null if the property was
not in the environment before

throws NamingException
Binds a name to an object.

bind
public void bind(String 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
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.
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(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: Not supported.
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

public Context createSubcontext(String name)

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

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().

getNameInNamespace
public String getNameInNamespace()
throws NamingException
Retrieves the full name of this context within its own namespace.
Not implemented.
- 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
- a name parser that can parse compound names into their atomic
components

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.
name
- the name of the context to list
- an enumeration of the names and class names of the
bindings in this context. Each element of the
enumeration is of type NameClassPair.

rebind
public void rebind(Name name,
Object obj)
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.

from the target context--that named by all but the terminal
atomic part of name.
This method is idempotent.
