java.lang.Object

org.apache.flink.cep.pattern.Quantifier

public class Quantifier
extends Object

A quantifier describing the Pattern. There are three main groups of Quantifier.

1. Single
2. Looping
3. Times

Each Pattern can be optional and have a Quantifier.ConsumingStrategy. Looping and Times also hava an additional inner consuming strategy that is applied between accepted events in the pattern.
