Package io.github.mmm.validation

Class ComposedValidator<V>

java.lang.Object

io.github.mmm.validation.AbstractValidator<V>

io.github.mmm.validation.AbstractComposedValidator<V,V>

io.github.mmm.validation.ComposedValidator<V>

Type Parameters:

V - is the generic type of the value to validate.

All Implemented Interfaces:

Composable<Validator<?>>, Validator<V>, Iterable<Validator<?>>

public class ComposedValidator<V>
extends AbstractComposedValidator<V,V>

Validator that is composed out of a set of individual validators given at construction. It will always invoke all contained validators when a validation is performed.

Since:

1.0.0

Constructor Details

ComposedValidator

@SafeVarargs
public ComposedValidator(Validator<? super V>... validators)

The constructor.

Parameters:

validators - are the child Validators to compose.

Method Details

getId

public String getId()

Description copied from class: AbstractValidator

AbstractValidator only provides a default implementation of this method.
ATTENTION:
This default implementation returns the simple class name of the actual Validator implementation. This strategy is chosen for simplicity when implementing a new Validator. To ensure stable IDs override this method and return a string constant. This shall at least be done when the name of the class is changed to provide backwards compatibility.

Specified by:

getId in interface Validator<V>

Overrides:

getId in class AbstractValidator<V>

Returns:

the identifier of this Validator.

• ValidationResult.getCode()

validate

public ValidationResult validate(V value,
 Object valueSource)

Description copied from interface: Validator

This method validates the given value.

Parameters:

value - is the value to validate.

valueSource - is the source describing the origin of the given value. The source needs to have a reasonable string-representation as this may be displayed to the end-user to locate the source of the failure. In most cases it is suitable to directly pass a String.

Returns:

the ValidationResult.
