    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.
    
    Specified by:
    
    unbind in interface javax.naming.Context
    
    Parameters:
    name - the name to bind; may not be empty

    javax.naming.NamingException - if a naming exception is encountered
  - unbind
```
public void unbind(java.lang.String name)
            throws javax.naming.NamingException

            throws javax.naming.NamingException
```
    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.
    
    Specified by:
    
    rename in interface javax.naming.Context
    
    Parameters:
    oldName - the name of the existing binding; may not be empty

  - 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
    
    javax.naming.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
    
    javax.naming.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

    Specified by:
    
    lookupLink in interface javax.naming.Context
    
    Parameters:
    name - the name of the object to look up

                                      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:
    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
  - getNameParser
```
public javax.naming.NameParser getNameParser(java.lang.String name)
                                      throws javax.naming.NamingException
```
    Retrieves the parser associated with the named context.
    
    Specified by:
    
    getNameParser in interface javax.naming.Context
    
    Parameters:

                              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
    
    Throws:
    
    javax.naming.NamingException - if a naming exception is encountered
  - composeName
```

    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:
    
    javax.naming.NamingException - if a naming exception is encountered
  - addToEnvironment
```
public java.lang.Object addToEnvironment(java.lang.String propName,
                                java.lang.Object propVal)
                                  throws javax.naming.NamingException
```
    Adds a new environment property to the environment of this context. If the property already exists, its value is overwritten.
    
    Specified by:
    
    addToEnvironment in interface javax.naming.Context
    
    Parameters:
    propName - the name of the environment property to add; may not be null
    propVal - the value of the property to add; may not be null
    
    Throws:
    
    javax.naming.NamingException - if a naming exception is encountered
  - removeFromEnvironment
```
public java.lang.Object removeFromEnvironment(java.lang.String propName)
                                       throws javax.naming.NamingException
```
    Removes an environment property from the environment of this context.
    
    Specified by:
    
    removeFromEnvironment in interface javax.naming.Context
    
    Parameters:
    propName - the name of the environment property to remove; may not be null
    
    Throws:
    
    javax.naming.NamingException - if a naming exception is encountered
  - getEnvironment
```
public java.util.Hashtable<?,?> getEnvironment()
                                        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:
    
    javax.naming.OperationNotSupportedException - if the naming system does not have the notion of a full name
    
    javax.naming.NamingException - if a naming exception is encountered
  - getBoundContext
```
protected javax.naming.Context getBoundContext()
                                        throws javax.naming.NamingException
```
    Get the bound context.
    
    Throws:
    
    javax.naming.NamingException
  - parseName
```
protected java.lang.String parseName(java.lang.String name)
                              throws javax.naming.NamingException
```
    Strips the URL header.
    
    Returns:
    the parsed name
    
    Throws:
    
    javax.naming.NamingException - if there is no "java:" header or if no naming context has been bound to this thread
  - parseName
```
protected javax.naming.Name parseName(javax.naming.Name name)
                               throws javax.naming.NamingException
```
    Strips the URL header.
    
    Returns:
    the parsed name
    
    Throws:
    
    javax.naming.NamingException - if there is no "java:" header or if no naming context has been bound to this thread
