[Java] Class ReplicaSetConfig

java.lang.Object
  brooklyn.entity.nosql.mongodb.ReplicaSetConfig

public class ReplicaSetConfig

Simplifies the creation of configuration objects for Mongo DB replica sets.

A configuration object is structured like this: 

 {
	"_id" : "replica-set-name",
 	"version" : 3,
	"members" : [
		{ "_id" : 0, "host" : "Sams.local:27017" },
		{ "_id" : 1, "host" : "Sams.local:27018" },
		{ "_id" : 2, "host" : "Sams.local:27019" }
	]
 }
To add or remove servers to a replica set you must redefine this configuration (run replSetReconfig on the primary) with the new members list and the version updated.
