ctx - current schema parsing context

fieldName - field name (keyword) in JSON object for which Evaluator should be created

fieldNode - value of field in JSON object

Returns:

If this factory supports given field name (keyword) it should return corresponding Evaluator wrapped in Optional, Optional.empty() otherwise.

compose
