Class PluginManager

java.lang.Object

org.dmd.dmp.server.servlet.base.PluginManager

All Implemented Interfaces:

org.dmd.util.parsing.DmcUncheckedOIFHandlerIF

public class PluginManager
extends Object
implements org.dmd.util.parsing.DmcUncheckedOIFHandlerIF

The PluginManager reads a plugin configuration and loads and instantiates the plugins specified. Certain plugin roles are required in order for the application to function properly. These roles include:

• Cache - which provides centralized access to named objects and allows for CRUDE operations - Create, Read, Update, Delete and Events associated with the objects it manages. A cache implementation MUST be Runnable in order to allow for proper sequencing of operations and events.
• SecurityManager - provides user authentication and session management.
