In order to migrate all the transformers in which any of operatorTransformer, operandTransformer and resultTransformer is defined as a JSON string into the transformers which define the transformation rule in native Java code, the following code changes are made in this PR:

  • Adding some classes to implement the transformers which extends SignatureBasedConditionSqlCallTransformer and the specific transformation logic is defined as native Java code including
    • DateDiffOperatorTransformer
    • DateSubOperatorTransformer
    • DateAddOperatorTransformer
    • DecodeOperatorTransformer
    • RegexpExtractOperatorTransformer
    • ModOperatorTransformer
    • TruncateOperatorTransformer
    • RandomIntegerOperatorWithTwoOperandsTransformer
    • RandomOperatorWithOneOperandTransformer
  • Removing the code related to operatorTransformer, operandTransformer and resultTransformer defined as JSON strings out of the class of SignatureBasedConditionSqlCallTransformer

To be noted that this PR is based on PR #349
