class_docstr: Base class for DeserializationSchema. The deserialization schema describes how to turn the byte
  messages delivered by certain data sources (for example Apache Kafka) into data types (Java/
  Scala objects) that are processed by Flink.
  
  In addition, the DeserializationSchema describes the produced type which lets Flink create
  internal serializers and structures to handle the type.

label_desc: Use image node_id 1 to create a new DeserializationSchema object from inherited base classes: object with example: obj = DeserializationSchema(j_deserialization_schema)
