This logic is very specific to this utility so C API at this time may not be necessary. Also, we have C APIs to get list of operator names, then a C API to get by operator name the details of the operator params etc. so that should helps majority of users. 2. Refactored the helper code to split the responsibility. Thanks. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
