org.apache.flink.cep.pattern.conditions.IterativeCondition<T>

org.apache.flink.cep.pattern.conditions.RichIterativeCondition<T>

org.apache.flink.cep.pattern.conditions.RichCompositeIterativeCondition<T>

Type Parameters:

T - Type of the element to filter

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.common.functions.RichFunction

Direct Known Subclasses:

RichAndCondition, RichNotCondition, RichOrCondition

public abstract class RichCompositeIterativeCondition<T>
extends RichIterativeCondition<T>

A base class of composite IterativeCondition conditions such as RichAndCondition, RichOrCondition and RichNotCondition, etc. It handles the open, close and setRuntimeContext for the nested IterativeCondition conditions.
