Deserialize binary Thrift message in Scala

Question

I am trying to desrialize a binary message in Scala:

val deserializer = new TDeserializer(new TBinaryProtocol.Factory());
    try {
      val obj = deserializer.deserialize(new ClientError{}, input._2.toArray)

Where ClientError is the trait generated with Scrooge from a Thrift file. The problem is, that deserialize() expects a TBase object, but TBase is an interface. How do I do this? Do I have to create a new class which implements both? Thx for any help!

Answer 1

Try this:

def decode(bytes: Array[Byte]): ClientError = {
  val protocolFactory = new TBinaryProtocol.Factory
  val buffer = new TMemoryInputTransport(bytes)
  val proto = protocolFactory.getProtocol(buffer)
  ClientError.decode(proto)
}

Answer 2

def getClientError(binaryData: Array[Byte]) : ClientError = {
         val tdser = new TDeserializer();  
         val cliErr = new ClientError()
         tdser.deserialize(cliErr, binaryData)
         return cliErr 
}
