org.glassfish.comms.api.datacentric.DataCentricUtil
This is a utility for accessing and querying the Data Centric entities, for example the consistent hash for all server instances in the cluster.
The interface is implemented by the container and is made available for applications through a ServletContext attribute via the string constant {@link #CONTEXT_ATTRIBUTE_NAME} which is a member of the interface.
Example:
```
 : DataCentricUtil dcu = (DataCentricUtil) getServletContext().getAttribute(DataCentricUtil.CONTEXT_ATTRIBUTE_NAME); : 
```

     *
     * @return the server instance where the CLB is presently routing the id
     *
     */
    public static String getCurrentServerInstance(String sasId) {
  DataCentricUtil dcu = DataCentricUtilHolder.getInstance();
  String instance;
  String key = SipApplicationSessionUtil.getSipApplicationKey(sasId);
  if (dcu instanceof DataCentricUtilImpl)
      instance = ((DataCentricUtilImpl) dcu).getCLBServerInstance(key);
  else instance = dcu.getActualServerInstance(key);
  return instance;
    }
