checkEvaluationArgs

checkEvaluationArgs(reference?, input?): void
Check if the evaluation arguments are valid.
Parameters
- Optional reference: string
  The reference label.
- Optional input: string
  The input string.
Returns void
Throws
If the evaluator requires an input string but none is provided, or if the evaluator requires a reference label but none is provided.
