Interface DynamicPropertyHandler
- 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:
- Build an implementation of the DynamicPropertyHandler interface
for the desired collection type.
- 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']"
