org.apache.tinkerpop.gremlin.structure.io.graphson.JsonParserConcat

public class JsonParserConcat
extends JsonParserSequence

Utility class to easily concatenate multiple JsonParsers. This class had to be implemented because the class it is extending, JsonParserSequence, inevitably skips a token when switching from one empty parser to a new one. I.e. it is automatically calling JsonParser#nextToken() when switching to the new parser, ignoring the current token. This class is used for high performance in GraphSON when trying to detect types.
