All Implemented Interfaces:

Map<String,Object>, Backing

public class CollectorBacking
extends BasicBacking

A basic implementation for the backing of a ContextContainter. It uses a HashMap, but is also writes every entry to the temporary to the page-context, to make them available to JSP2's expression language, unless the 'ELIgnored' parameter of the MMBase taglib is true, or no pageContext is given in the constructor.

Since:

MMBase-1.9.2
