Class InvokerMessageProcessor

java.lang.Object

org.mule.runtime.api.meta.AbstractAnnotatedObject

org.mule.runtime.core.processor.InvokerMessageProcessor

All Implemented Interfaces:

Function<org.reactivestreams.Publisher<Event>,org.reactivestreams.Publisher<Event>>, org.mule.runtime.api.lifecycle.Initialisable, org.mule.runtime.api.meta.AnnotatedObject, FlowConstructAware, Processor, ReactiveProcessor

public class InvokerMessageProcessor
extends org.mule.runtime.api.meta.AbstractAnnotatedObject
implements Processor, org.mule.runtime.api.lifecycle.Initialisable, FlowConstructAware

InvokerMessageProcessor invokes a specified method of an object. An array of argument expressions can be provided to map the message to the method arguments. The method used is determined by the method name along with the number of argument expressions provided. The results of the expression evaluations will automatically be transformed where possible to the method argument type. Multiple methods with the same name and same number of arguments are not supported currently.
