Interface Validated<T>

Type Parameters:

T - the type of value being validated

All Superinterfaces:

Iterable<Validated<T>>

All Known Implementing Classes:

Validated.Both, Validated.Either, Validated.Invalid, Validated.Missing, Validated.None, Validated.Secret, Validated.Valid

public interface Validated<T>
extends Iterable<Validated<T>>

A container object which may or may not contain a valid value. If a value is valid, isValid() returns true. If the value is invalid, the object is considered invalid and isValid() returns false.

Method Details

isValid

boolean isValid()

isInvalid

default boolean isInvalid()

failures

default List<Validated.Invalid<T>> failures()

validSecret

static Validated.Secret validSecret(String property,
 String value)

none

static <T> Validated.None<T> none()

valid

static <T> Validated.Valid<T> valid(String property,
 @Nullable T value)

test

static <T> Validated<T> test(String property,
 String message,
 @Nullable T value,
 Predicate<T> test)

Validate that the Predicate will evaluate to 'true' on the supplied value. When the Predicate evaluates to 'false' the error message will be of the form:

"[property] was '[value]' but it [message]"

Type Parameters:

T - The property value type.

Parameters:

property - The property name to test

message - The failure message if the test doesn't pass

value - The value of the property

test - The test predicate

Returns:

A validation result

testNone

static <T,
V> Validated<T> testNone(String property,
 String message,
 @Nullable V value,
 Predicate<V> test)

Validate that the Predicate will evaluate to 'true' on the supplied value. Will return a Validated.None if the value is valid.

This allows validation of a value that is not the intended return value.

When the Predicate evaluates to 'false' the error message will be of the form:

"[property] was '[value]' but it [message]"

Type Parameters:

T - The property value type.

Parameters:

property - The property name to test

message - The failure message if the test doesn't pass

value - The value of the property

test - The test predicate

Returns:

A validation result

required

static <T> Validated<T> required(String property,
 @Nullable T value)

notBlank

static Validated<String> notBlank(String property,
 @Nullable String value)

missing

static <T> Validated.Missing<T> missing(String property,
 @Nullable T value,
 String message)

invalid

static <T> Validated.Invalid<T> invalid(String property,
 @Nullable Object value,
 String message)

invalid

static <T> Validated.Invalid<T> invalid(String property,
 @Nullable Object value,
 String message,
 @Nullable Throwable exception)

and

default Validated<T> and(Validated<? extends T> validated)

or

default Validated<T> or(Validated<? extends T> validated)

getValue

@Nullable T getValue()
