Class StompServerHandler

java.lang.Object

io.vertx.reactivex.ext.stomp.StompServerHandler

All Implemented Interfaces:

Handler<ServerFrame>, io.vertx.lang.rx.RxDelegate

public class StompServerHandler
extends Object
implements io.vertx.lang.rx.RxDelegate, Handler<ServerFrame>

STOMP server handler implements the behavior of the STOMP server when a specific event occurs. For instance, if let customize the behavior when specific STOMP frames arrives or when a connection is closed. This class has been designed to let you customize the server behavior. The default implementation is compliant with the STOMP specification. In this default implementation, not acknowledge frames are dropped.

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
