java.lang.Objectjava.util.AbstractMap
org.apache.struts2.dispatcher.ApplicationMap
public class ApplicationMap
A simple implementation of the Map interface to handle a collection of attributes and
init parameters in a ServletContext object. The entrySet() method
enumerates over all servlet context attributes and init parameters and returns a collection of both.
Note, this will occur lazily - only when the entry set is asked for.
