Interface ElasticServiceManagers

All Superinterfaces:

AdminAware, DumpProvider, Iterable<ElasticServiceManager>

public interface ElasticServiceManagers
extends AdminAware, Iterable<ElasticServiceManager>, DumpProvider

Provides simple means to get all the current managers, as well as as registering for manager life-cycle (added and removed) events.

 Disclaimer: This interface and the elastic data grid functionality is provided as a technology preview in XAP 7.1. 
 As such, it is subject to API and behavior changes in the next XAP releases without going through the usual deprecation process 
 of the XAP API.
