getChildForPath

public BaseConfiguration getChildForPath(java.lang.String path)
                                  throws javax.naming.NameNotFoundException

This method traverses the child hierarchy (from the top) and returns the configuration object associated with the path. This method will in effect split the path in its components and recursively call getChild() to drill down to the last object in the path.

Specified by:

getChildForPath in interface BaseConfiguration

Parameters:

path - The complete path to an object (as returned by getPath())

Returns:

The configuration object associated with the path

Throws:

This method returns the path to this object. The path can be used to traverse a hierarchy of configuration objects/configuration values. The preferred name is the parent's name for this configuration object since we use the getChild() method to map between names and config objects. We do this since the name of this object can be different than the parent's name for the object, which basically happens when the parent container has several objects with the same name.

Specified by:

getPath in interface BaseConfiguration

Returns:

The path to this configuration object

Returns:

true if this object was removed; false if it could not be removed.
