Tranquility API - Example to construct JSON Spec via Java API

Can someone point me out to Java API Example to construct Tranquility JSON spec via java code? Managing properties between environments has become a challenge when the spec is maintained in the json file.

Thanks!

Take a look at DruidBeams.builder, docs are here: http://static.druid.io/tranquility/api/latest/#com.metamx.tranquility.druid.DruidBeams$
