class BaseValidator[T] extends Validator[T]
Simplifies base validator implementation. Validators typically consist of an assertion/test and a resulting violation; this implementation takes two functions that describe this behavior and wires the appropriate logic. For example:
class IsNull extends BaseValidator[ AnyRef ]( _ == null, _ -> "is not a null" )
- T
The object type this validator operates on.

new
BaseValidator(test: (T) ⇒ Boolean, failure: (T) ⇒ Failure)
- 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.

def
compose[U](g: (U) ⇒ T): Validator[U]
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 resultingT
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 thevalid
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
