java.lang.Object
   java.util.AbstractMap
      org.apache.struts2.dispatcher.ApplicationMap

ApplicationMap
public class ApplicationMap extends AbstractMap implements Serializable(Code)
A simple implementation of the java.util.Map interface to handle a collection of attributes and init parameters in a javax.servlet.ServletContext object. The ApplicationMap.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.



Constructor Summary
public  ApplicationMap(ServletContext ctx)
     Creates a new map object given the servlet context.

Method Summary
public  voidclear()
     Removes all entries from the Map and removes all attributes from the servlet context.
public  SetentrySet()
     Creates a Set of all servlet context attributes as well as context init parameters.
public  Objectget(Object key)
     Returns the servlet context attribute or init parameter based on the given key.
public  Objectput(Object key, Object value)
     Sets a servlet context attribute given a attribute name and value.
Parameters:
  key - the name of the attribute.
Parameters:
  value - the value to set.
public  Objectremove(Object key)
     Removes the specified servlet context attribute.
Parameters:
  key - the attribute to remove.
