All Implemented Interfaces:

UseCaseMethodInvoker

public final class SerializingMethodInvoker
extends Object
implements UseCaseMethodInvoker

Description copied from interface: UseCaseMethodInvoker

Takes the use case instance and the current event to invoke the method on the use case instance. The Deserializer is used to deserialize the event into the parameters of the method. The method's return value is deserialized with the Serializer.

Specified by:

invoke in interface UseCaseMethodInvoker

Parameters:

useCase - the use case instance

event - the request message

requestDeserializer - the Deserializer for the parameters

responseSerializer - the Serializer for the return value

parameterInjector - the configured ParameterInjector with all injections

Returns:

the serialized return value as Map

Throws:

MethodInvocationException - when the method cannot be invoked

ClassCastException - when the event is not a valid Map of type <String, Object>

Exception - all exceptions declared by the use case method are rethrown
