class BoolField

popcorn :: BoolField

Check if a field is a Bool

var validator = new ObjectValidator
validator.add new BoolField("field", required=false)
assert validator.validate("""{}""")
assert validator.validate("""{ "field": true }""")
assert validator.validate("""{ "field": false }""")
assert not validator.validate("""{ "field": "foo" }""")

validator = new ObjectValidator
validator.add new BoolField("field")
assert not validator.validate("""{}""")
assert validator.validate("""{ "field": true }""")
assert validator.validate("""{ "field": false }""")
assert not validator.validate("""{ "field": "foo" }""")

No type conversion is applied on the input value:

assert not validator.validate("""{ "field": "true" }""")
assert not validator.validate("""{ "field": 1 }""")
assert not validator.validate("""{ "field": [true] }""")
