Class Switch

java.lang.Object

com.sdicons.json.validator.predicates.Predicate

com.sdicons.json.validator.predicates.Switch

All Implemented Interfaces:

Validator

public class Switch
extends Predicate

The switch validator is a convenience one. It is a subset of the or validator, but the problem with the or validator is that it does a bad job for error reporting when things go wrong. The reason is that all rules fail and it is not always clear why, because the reason a rule fails might be some levels deeper. The switch validator selects a validator based on the value of a property encountered in the value being validated. The error produced will be the one of the selected validator. The first applicable validator is used, the following ones are ignored.

  
  {
     "name" :"Switch test",
     "type" :"switch",
     "key":"discriminator",
     "case" : [{"values":["a", "b", "c", 1, 2, 3], "rule":{"type":"true"}}]
 }
