class ReceiveBuilder extends AnyRef
Used for building a partial function for AbstractActor.createReceive().
There is both a match on type only, and a match on type and predicate.
Inside an actor you can use it like this:
Example:
@Override
public Receive createReceive() {
return receiveBuilder()
.match(Double.class, d -> {
getSender().tell(d.isNaN() ? 0 : d, self());
})
.match(Integer.class, i -> {
getSender().tell(i * 10, self());
})
.match(String.class, s -> s.startsWith("foo"), s -> {
getSender().tell(s.toUpperCase(), self());
})
.build()
);
}
