Examples of DynamicPropertyHandler

org.apache.commons.jxpath.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 {@link JXPathIntrospector#registerDynamicClass JXPathIntrospector.registerDynamicClass(class, handlerClass)}

JXPath allows access to dynamic properties using these three formats:

"myMap/myKey"
"myMap[@name = 'myKey']"
"myMap[name(.) = 'myKey']"
