Functions

addMessageHandler fun <Q : ServiceRequestMessage, R : Any> addMessageHandler(topic: String, handler: (Q) -> R, exceptionConsumer: (Message, Exception) -> Unit): MessageHandlerRegistration

Register a handler for a message topic. In comparison to using net.addMessageHandler() this manages a lot of common boilerplate code. Exceptions are caught and passed to the provided consumer. If you just want a simple acknowledgement response with no content, use com.r3corda.core.messaging.Ack.
