class ReceiveBuilder extends AnyRef
Used for building a partial function for Actor.receive()
.
There is both a match on type only, and a match on type and predicate.
Inside an actor you can use it like this with Java 8 to define your receive method.
Example:
@Override public Actor() { receive(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() ); }
