Validator

A validator over some type T.

Overview

An Accord validator is a function T => Result, where T is the type of the object under validation and Result is an instance of com.wix.accord.Result.

Implementation note: While theoretically a validator can be defined as a type alias, in practice this doesn't allow to specify an error message when it's implicitly missing at the call site.

T: The object type this validator operates on.

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 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.
