22. xml?

24. so what?

26. MuleContex context = Mule.newMuleContext();
Flow myFlow = new Flow();
myFlow.setName("MyFlow");
InboundEndpoint myIn = new GenericInboundEndpoint();
myIn.setURL("file:///Users/porcelli/in");
OutboundEndpoint myOut = new GenericOutboundEndpoint();
myIn.setURL("file:///Users/porcelli/out");
myFlow.setInbound(myIn);
myFlow.addMessageProcessor(myOut);
context.addFlow(myFlow);
ok?
muleContext.start();

27. NO!

28. DSL!

29. goals...
➡ Expressive & Natural
➡ Easy to Use & Learn
➡ Hard to Misuse
➡ Extensible

30. Mule.newMuleContext(new AbstractModule() {
@Override
public void configure() {
flow("MyFlow")
.from("file:///Users/porcelli/in")
.send("file:///Users/porcelli/out");
}
}).start();

31. remember?
MuleContex context = Mule.newMuleContext();
Flow myFlow = new Flow();
myFlow.setName("MyFlow");
InboundEndpoint myIn = new GenericInboundEndpoint();
myIn.setURL("file:///Users/porcelli/in");
OutboundEndpoint myOut = new GenericOutboundEndpoint();
myIn.setURL("file:///Users/porcelli/out");
myFlow.setInbound(myIn);
myFlow.addMessageProcessor(myOut);
context.addFlow(myFlow);
muleContext.start();

32. feedback?

33. cloud...
final TwitterConnector twitterConnector = new TwitterConnector();
twitterConnector.setConsumerKey("key");
twitterConnector.setConsumerSecret("secret");
twitterConnector.setOathToken("token");
Mule.newMuleContext(new AbstractModule() {
@Override
public void configure() {
flow("MyFlow")
.from("file:///Users/porcelli/tweet")
.transformTo(String.class)
.process(twitterConnector.statusesUpdate(payload()));
}
}).start();
