org.axonframework.eventhandling.replay.ReplayContextParameterResolverFactory

All Implemented Interfaces:

ParameterResolverFactory

public class ReplayContextParameterResolverFactory
extends Object
implements ParameterResolverFactory

An implementation of the ParameterResolverFactory which resolves the parameter annotated with ReplayContext. Will resolve the parameter if the Message is a TrackedEventMessage, containing a ReplayToken with a matching context of that type. Otherwise, it will resolve always to null.

This parameter resolver will always match to prevent missing event handlers.
