Class AppContentManager

java.lang.Object
  |
  +--com.xmlserv.app.contentmanagement.AppContentManager

All Implemented Interfaces:

ContentManager

public class AppContentManager

extends java.lang.Object

implements ContentManager

A ContentManager implementation reading its configuration from the DB. The configuration table has the following format:

 rolegroup	INT
 context		VARCHAR(255)	NOT NULL
 classname	VARCHAR(255)	NOT NULL
 

The rolegroup is a reference to the users rolegroup, context is the part of the site this module entry refers to, classname is the implementing class (implementing the interface BackendModule.
The context (using the default context separator) looks like this:
/<rolegroupid>/context path 1/context path 2/.../context path n
i.e. it looks like a path with the rolegroup id prepended. This is used to locate BackendModules that are configured in the various hierarchy layers.
An example:
The context /0/party/agenda/list.xml leads to the following contexts being evaluated:

1. /0/party/agenda/list.xml
2. /0/party/agenda
3. /0/party
4. /0

This can be used to define site wide defaults (context /0, defaults for parts of the site (/0/party) etc.
