public BaseContext() 
{
        super();
}

 public BaseContext(Hashtable env) 
{
        super(env);
}

 public Object addToEnvironment(String propName,
    Object propVal) throws NamingException 
{
        return env.put(propName, propVal);
}

Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten.

 public  void bind(Name name,
    Object obj) throws NamingException 
{
        bind(name, obj, null, false);
}

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.

 public  void bind(String name,
    Object obj) throws NamingException 
{
        bind(string2Name(name), obj, null, false);
}

Binds a name to an object.

 public  void close() throws NamingException 
{
        // We don't own the env., but the clone
        env.clear();
}

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.

 public Name composeName(Name name,
    Name prefix) throws NamingException 
{
        prefix = (Name) prefix.clone();
        return prefix.addAll(name);
}

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.

 public String composeName(String name,
    String prefix) throws NamingException 
{
        return prefix + "/" + name;
}

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

 public Context createSubcontext(Name name) throws NamingException 
{
        return createSubcontext(name, null);
}

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.

 public Context createSubcontext(String name) throws NamingException 
{
        return createSubcontext(string2Name(name), null);
}

 public  void destroySubcontext(Name name) throws NamingException 
{
        unbind(name, true);
}

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.

 public  void destroySubcontext(String name) throws NamingException 
{
        unbind(string2Name(name), true);
}

Destroys the named context and removes it from the namespace.

 public Hashtable getEnvironment() throws NamingException 
{
        return env;
}

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().

 public String getNameInNamespace() throws NamingException 
{
        throw new OperationNotSupportedException();
}

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.

 public NameParser getNameParser(Name name) throws NamingException 
{
        while ((!name.isEmpty()) && (name.get(0).length() == 0))
            name = name.getSuffix(1);
        if (name.isEmpty())
            return nameParser;
        if (name.size()  > 1) {
            Object obj = lookup(name.get(0));
            if (obj instanceof Context) {
                return ((Context) obj).getNameParser(name.getSuffix(1));
            } else {
                throw new NotContextException(name.toString());
            }
        }
        return nameParser;
}

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).

 public NameParser getNameParser(String name) throws NamingException 
{
        return getNameParser(new CompositeName(name));
}

Retrieves the parser associated with the named context.

 public NamingEnumeration list(String name) throws NamingException 
{
        return list(string2Name(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.

 public NamingEnumeration list(Name name) throws NamingException 
{
        return new NamingContextEnumeration(getChildren(), this, false);
}

 public NamingEnumeration listBindings(Name name) throws NamingException 
{
        return new NamingContextEnumeration(getChildren(), this, true);
}

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.

 public NamingEnumeration listBindings(String name) throws NamingException 
{
        return listBindings(string2Name(name));
}

 public Object lookup(Name name) throws NamingException 
{
        return lookup(name, true);
}

Retrieves the named object. If name is empty, returns a new instance of this context (which represents the same naming context as this context, but its environment may be modified independently and it may be accessed concurrently).

 public Object lookup(String name) throws NamingException 
{
        return lookup(string2Name(name), true);
}

Retrieves the named object.

 public Object lookupLink(Name name) throws NamingException 
{
        return lookup(name, false);
}

Retrieves the named object, following links except for the terminal atomic component of the name. If the object bound to name is not a link, returns the object itself.

 public Object lookupLink(String name) throws NamingException 
{
        return lookupLink(string2Name(name));
}

Retrieves the named object, following links except for the terminal atomic component of the name.

 public  void rebind(Name name,
    Object obj) throws NamingException 
{
        bind(name, obj, null, true);
}

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.

 public  void rebind(String name,
    Object obj) throws NamingException 
{
        bind(string2Name(name), obj, null, true);
}

Binds a name to an object, overwriting any existing binding.

 public Object removeFromEnvironment(String propName) throws NamingException 
{
        return env.remove(propName);
}

Removes an environment property from the environment of this context.

 public  void rename(String oldName,
    String newName) throws NamingException 
{
        rename(string2Name(oldName), string2Name(newName));
}

Binds a new name to the object bound to an old name, and unbinds the old name. Both names are relative to this context. Any attributes associated with the old name become associated with the new name. Intermediate contexts of the old name are not changed.

 public  void rename(Name oldName,
    Name newName) throws NamingException 
{
            // Override if needed
            Object value = lookup(oldName, false);
            bind(newName, value, null, false);
            unbind(oldName, true);
}

 public NamingEnumeration search(Name name,
    String filter,
    SearchControls cons) throws NamingException 
{
        return search(name.toString(), filter, cons);
}

Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

 public NamingEnumeration search(String name,
    String filter,
    SearchControls cons) throws NamingException 
{
        throw new OperationNotSupportedException();
}

Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

 public NamingEnumeration search(Name name,
    String filterExpr,
    Object[] filterArgs,
    SearchControls cons) throws NamingException 
{
        return search(name.toString(), filterExpr, filterArgs, cons);
}

Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

 public NamingEnumeration search(String name,
    String filterExpr,
    Object[] filterArgs,
    SearchControls cons) throws NamingException 
{
        throw new OperationNotSupportedException();
}

Searches in the named context or object for entries that satisfy the given search filter. Performs the search as specified by the search controls.

 public  void unbind(Name name) throws NamingException 
{
        unbind(name, false);
}

Unbinds the named object. Removes the terminal atomic name in name from the target context--that named by all but the terminal atomic part of name.

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.

 public  void unbind(String name) throws NamingException 
{
        unbind(string2Name(name), false);
}
