class NullSafeValidator[T <: AnyRef] extends BaseValidator[T]

An extension to com.wix.accord.BaseValidator that transparently fails on nulls.

T

The object type this validator operates on.

    test

    The predicate that determines whether or not validation is successful.

    failure

    A generator function for producing com.wix.accord.Failures if validation fails. The helper methods in com.wix.accord.ViolationBuilder can be used to simplify this task.

    onNull

    The resulting failure for nulls. Defaults to com.wix.accord.Validator.nullFailure.

  8. def compose[U](g: (U) ⇒ T): Validator[U]

    Permalink

    Adapts this validator to a type U.

    Adapts this validator to a type U. Each application of the new validator applies the the specified extractor function, and validates the resulting T via this validator. This enables explicit validator composition, which is especially useful for defining new, complex combinators. At the validator definition site, it is recommended to use the valid operation provided by the DSL instead.

    Important note: the specified extractor function must be able to safely handle nulls!

    U

    The target type of the adaption.

    g

    An extractor function from U => T.

    returns

    An adapted validator over type U.
