java.lang.Object

org.apache.beam.fn.harness.control.FinalizeBundleHandler

public class FinalizeBundleHandler
extends java.lang.Object

A bundle finalization handler that expires entries after a specified amount of time.

Callers should register new callbacks via registerCallbacks(java.lang.String, java.util.Collection<org.apache.beam.fn.harness.control.FinalizeBundleHandler.CallbackRegistration>) and fire existing callbacks using finalizeBundle(org.apache.beam.model.fnexecution.v1.BeamFnApi.InstructionRequest).
