public interface Twister2Worker

Method Summary

Modifier and Type	Method and Description
void	execute(WorkerEnvironment workerEnv) This is the main point of entry for Twister2 jobs.

Method Detail

execute

void execute(WorkerEnvironment workerEnv)

This is the main point of entry for Twister2 jobs. Every job should implement this interface. When a job is submitted, a class implementing this interface gets instantiated and executed by Twister2. As the first thing in the execute method, users are expected to initialize the proper environment object: for batch jobs: BatchTSetEnvironment for streaming jobs: StreamingTSetEnvironment
