org.nebulaframework.grid.cluster.manager.ClusterManager
{@code ClusterManager} manages a Cluster of {@code GridNode}s in Nebula Framework. This is key server-side class in Nebula Framework, which provides server-side facilities with in the cluster.
Each core functionality provided by the {@code ClusterManager} is provided througha service, and the services are as follows:
- {@link ClusterRegistrationService}
- {@link ClusterJobService}
- {@link ServiceMessageSender}
{@code ClusterRegistrationService} is exposed directly as a remote service and{@code ClusterJobService} is exposed through {@link ClusterManagerServicesFacade}, which will also be used for other services in the future implementation.
Note : This class is managed by Spring Container. If it is required to use this outside Spring Container, please ensure that the {@link ClusterManager#afterPropertiesSet()} method is invoked after setting dependencies of the class. If deployed with in Spring Container, this will be automatically invoked by Spring itself.
