case class MemoryStream[A](id: Int, sqlContext: SQLContext)(implicit evidence$2: Encoder[A]) extends Source with Logging with Product with Serializable

A Source that produces value stored in memory as they are added by the user. This Source is primarily intended for use in unit tests as it can only replay data when the object is still available.
