Class HazelcastPersisterImp

java.lang.Object

com.jamonapi.distributed.HazelcastPersisterImp

All Implemented Interfaces:

JamonDataPersister

public class HazelcastPersisterImp
extends Object
implements JamonDataPersister

Class that interacts with HazelCast to save jamon data to it so data from any jvms in the hazelcast cluster can be visible via the jamon web app. Note in must cases hazelcast exceptions are not bubbled up in this class as I would still like jamon to be availalbe even if HazelCast has issues. The exceptions and stack traces can be seen in jamon however. Created by stevesouza on 7/6/14.
