    • convertJsonValueToDataValue

      public <T> T convertJsonValueToDataValue(jakarta.json.JsonValue jsonValue) throws jakarta.persistence.PersistenceException
      INTERNAL: Convert JSON value field to JDBC statement type. Postgres JSON storage type is JSONB and target Java type is PGobject.
      Overrides:
      convertJsonValueToDataValue in class org.eclipse.persistence.json.JsonPlatform
      Type Parameters:
      T - classification type
      Parameters:
      jsonValue - source JSON value field
      Returns:
      converted JDBC statement type
      Throws:
      jakarta.persistence.PersistenceException

      type - target class to return, this class will be used to cast returned value
      Returns:
      JSON data from JDBC ResultSet as String to be parsed by common JsonTypeConverter
      Throws:
      SQLException - if data could not be retrieved
