Examples of org.jaxen.BaseXPath

org.jaxen.BaseXPath
Base functionality for all concrete, implementation-specific XPaths.
This class provides generic functionalty for further-defined implementation-specific XPaths.

If you want to adapt the Jaxen engine so that it can traverse your own object model then this is a good base class to derive from. Typically you only really need to provide your own {@link org.jaxen.Navigator} implementation.
