java.lang.Object

org.alfresco.deployment.impl.server.DeploymentReceiverEngineImpl

All Implemented Interfaces:

java.lang.Runnable, DeploymentReceiverService, DeploymentReceiverTransport, DeploymentTargetRegistry, org.springframework.context.ApplicationContextAware

public class DeploymentReceiverEngineImpl
extends java.lang.Object
implements DeploymentReceiverTransport, DeploymentTargetRegistry, java.lang.Runnable, org.springframework.context.ApplicationContextAware

This is the implementation of the Alfresco Deployment Receiver Engine The Deployment Receiver Engine manages the communications with a host instance of alfresco and then delegates the deployment to one of the deployment targets. It also manages some server based functionality to do with start up / shut down and housekeeping.
