ByteBufferSerializer

trait ByteBufferSerializer extends AnyRef

Serializer between an object and a ByteBuffer representing that object.

Implementations should typically extend SerializerWithStringManifest and in addition to the ByteBuffer based toBinary and fromBinary methods also implement the array based toBinary and fromBinary methods. The array based methods will be used when ByteBuffer is not used, e.g. in Akka Persistence.

Note that the array based methods can for example be implemented by delegation like this:

 // you need to know the maximum size in bytes of the serialized messages
 val pool = new akka.io.DirectByteBufferPool(defaultBufferSize = 1024 * 1024, maxPoolEntries = 10)


// Implement this method for compatibility with `SerializerWithStringManifest`.
override def toBinary(o: AnyRef): Array[Byte] = {
  val buf = pool.acquire()
  try {
    toBinary(o, buf)
    buf.flip()
    val bytes = new Array[Byte](buf.remaining)
    buf.get(bytes)
    bytes
  } finally {
    pool.release(buf)
  }
}

// Implement this method for compatibility with `SerializerWithStringManifest`.
override def fromBinary(bytes: Array[Byte], manifest: String): AnyRef =
  fromBinary(ByteBuffer.wrap(bytes), manifest)

Abstract Value Members

  1. abstract def fromBinary(buf: ByteBuffer, manifest: String): AnyRef

    Produces an object from a ByteBuffer, with an optional type-hint; the class should be loaded using ActorSystem.dynamicAccess.
