Interface JsonSerializable

All Known Implementing Classes:

CardinalityEstimate, ExplainTreeNode, GenericSqlToStreamOperator, LoadEstimate, LoadProfile, SqlToRddOperator, SqlToStreamOperator

public interface JsonSerializable

This interface prescribes implementing instances to be able to provide itself as a WayangJsonObj. To allow for deserialization, implementing class should furthermore provide a static fromJson(JSONObject) method. Note that it is recommended to use the JsonSerializables utility to class to handle serialization.
