    • Mod

      public Mod(int modNumber, com.fasterxml.jackson.databind.JsonNode keysJsonNode, com.fasterxml.jackson.databind.JsonNode oldValuesJsonNode, com.fasterxml.jackson.databind.JsonNode newValuesJsonNode)
      Constructs a mod from the primary key values, the old state of the row and the new state of the row.
      Parameters:
      modNumber - Modification index number
      keysJsonNode - JSON object as String, where the keys are the primary key column names and the values are the primary key column values
      oldValuesJsonNode - JSON object as String, displaying the old state of the columns modified. This JSON object can be null in the case of an INSERT
      newValuesJsonNode - JSON object as String, displaying the new state of the columns modified. This JSON object can be null in the case of a DELETE

  • Method Details

    • oldValuesJsonNode

      public com.fasterxml.jackson.databind.JsonNode oldValuesJsonNode()
      The old column values before the modification was applied. This can be null when the modification was emitted for an INSERT operation. The values are returned as a JSON object (stringified), where the keys are the column names and the values are the column values.
      Returns:
      JSON object as String representing the old column values before the row was modified

    • newValuesJsonNode

      public com.fasterxml.jackson.databind.JsonNode newValuesJsonNode()
      The new column values after the modification was applied. This can be null when the modification was emitted for a DELETE operation. The values are returned as a JSON object (stringified), where the keys are the column names and the values are the column values.
      Returns:
      JSON object as String representing the new column values after the row was modified

    • keysJsonNode

      public com.fasterxml.jackson.databind.JsonNode keysJsonNode()
      The primary keys of this specific modification. This is always present and can not be null. The keys are returned as a JSON object (stringified), where the keys are the column names and the values are the column values.
      Returns:
      JSON object as String representing the primary key state for the row modified
