Class MainFilter

java.lang.Object
  org.mmbase.applications.media.filters.MainFilter

public class MainFilter

extends Object

This is the main class for the filter process. It maintains list of Filters (which content can be configured by the 'filters.xml' configuration file. It does not do any filtering itself, it is only the access to the actual filters, so filtering is completably configurable. Since there can be only one 'main' filter this class is a Singleton, and its one instance can be gotten by the getInstance function (and this is done by the Media builders when they need url representations to the stream they describe).
