DynamicPropertyHandler (Commons JXPath 1.3 API)

All Known Implementing Classes:

HttpSessionHandler, MapDynamicPropertyHandler, PageContextHandler, PageScopeContextHandler, ServletContextHandler, ServletRequestHandler
```
public interface DynamicPropertyHandler
```
A generic mechanism for accessing collections of name/value pairs. Examples of such collections are HashMap, Properties, ServletContext. In order to add support for a new such collection type to JXPath, perform the following two steps:
1. Build an implementation of the DynamicPropertyHandler interface for the desired collection type.
2. Invoke the static method JXPathIntrospector.registerDynamicClass(class, handlerClass)
JXPath allows access to dynamic properties using these three formats:
- "myMap/myKey"
- "myMap[@name = 'myKey']"
- "myMap[name(.) = 'myKey']"
