public final class MapTask
extends com.google.api.client.json.GenericJson

MapTask consists of an ordered set of instructions, each of which describes one particular low- level operation for the worker to perform in order to accomplish the MapTask's WorkItem. Each instruction must appear in the list before any instructions which depends on its output.

This is the Java data model class that specifies how to parse/serialize into the JSON that is transmitted over HTTP when working with the Dataflow API. For a detailed explanation see: https://developers.google.com/api-client-library/java/google-http-java-client/json
