org.apache.oodt.cas.resource.mux.StandardBackendManager

All Implemented Interfaces:

BackendManager

public class StandardBackendManager
extends Object
implements BackendManager

This manager keeps track of the mux-able backends for the resource manager. It effectively maps a queue to the backend that this queue feeds. It uses a private BackendSet to keep track of everything. For reference, a backend is a set of the following: 1. Batch manger, responsible for running jobs 2. Scheduler, responsible for scheduling a job to run 3. Monitor, responsible for managing nodes
