java.lang.Object

org.thales.punch.libraries.storm.util.LoadControlItem<T>

Type Parameters:

T - the associated attached instance

public class LoadControlItem<T>
extends Object

This class helps you keep track of the time it takes to acknowledge or fail a tuple.

You can associate a so called message id (storm terminology), and get it back as well so as to proceed with the tuple acknowledgement or failure logic. That message id is a pojo. It must not be serializable, it is kept until in memory locally to the emitter process.
