-hugegraph-client is a Java-written client of [HugeGraph](https://github.com/hugegraph/hugegraph), providing operations of graph, schema, gremlin, variables and traversals etc. All these operations are interpreted and translated into RESTful requests to HugeGraph Server. Besides, hugegraph-client also checks arguments, serializes and deserializes structures and encapsulates server exceptions.
