Impementation of SMPP 3.4 in Akka using akka-io.
Currently this is pretty bare-bones; constants have been mostly defined. Case classes exist for all the PDUs. Parsing PDUs from TCP and serializing them works.
- Tests
- EnquireLink timer
- Reading incoming PDUs
- Several parameter types need write implementations
- Solve commandLength problem
- Server example
- Parse valid TLVs
See Demo.scala for an example usage of an SMPP Client
val client = actorSystem.actorOf(Props(new SmppClient(new InetSocketAddress("localhost", 2775))))
client ! EnquireLink(16, 4)For the first version of this library, the coding style is purposely very simple. This leads to a certain amount of boilerplate that I would eventually like to rewrite to be more idiomatically-Scala. But the goal for now is that a Java or Python could easily understand all the code without learning many magic Scala features.
That being said, it is Scala idiomatic in terms of preferring immutable data, avoiding null, and
providing Async APIs.
There already exist several SMPP libraries in Java. To my knowledge, this is the only one in Scala.
- Cloudhopper is a nice async (netty) library that I've used from Scala before but suffers from very mutable APIs and lack of type safety. Fine for Java, but in Scala, this doesn't feel natural.
- jsmpp is a blocking Java API for SMPP.
- OpenSMPP Similar to JSMPP and also lacks immutable PDUs.
