This method is called after calling `filterRoutinesByParameterType()`, which will return `false` for the case when the incorrect name was specified in `argNames` list: https://github.com/apache/calcite/blob/1baee8524a8daa9c67f08f83080e269fc5938bc5/core/src/main/java/org/apache/calcite/sql/SqlUtil.java#L611 So at this point, we will have a list of functions, that have all parameter names from `argNames` list, if it is specified. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
