类 EventTimeTriggers

java.lang.Object

org.apache.flink.table.runtime.operators.window.triggers.EventTimeTriggers

public class EventTimeTriggers
extends Object

A Trigger that reacts to event-time timers. The behavior can be one of the following:

• fire when the watermark passes the end of the window (afterEndOfWindow()),

In the first case, the trigger can also specify an early and a late trigger. The early trigger will be responsible for specifying when the trigger should fire in the period between the beginning of the window and the time when the watermark passes the end of the window. The late trigger takes over after the watermark passes the end of the window, and specifies when the trigger should fire in the period between the endOfWindow and endOfWindow + allowedLateness.
