Class AbstractComposedValidator<V,C>

java.lang.Object

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

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

Type Parameters:

V - type of the value to validate.

C - type of the child value to validate using the child validators.

All Implemented Interfaces:

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

Direct Known Subclasses:

ComposedValidator, ProjectionValidator

public abstract class AbstractComposedValidator<V,C>
extends AbstractValidator<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:

getChildCount

public int getChildCount()

Specified by:

getChildCount in interface Composable<V>

Overrides:

getChildCount in class AbstractValidator<V>

getChild

public Validator<? super C> getChild(int index)

Specified by:

getChild in interface Composable<V>

Overrides:

getChild in class AbstractValidator<V>

append

public <T> Validator<T> append(Validator<?> validator)

Type Parameters:

T - type of the value to validate.

Parameters:

validator - the Validator to append.

Returns:

a new Validator instance composing this Validator with the given Validator.

append

public <T> Validator<T> append(Validator<?>... validators)

Type Parameters:

T - type of the value to validate.

Parameters:

validators - the Validators to append.

Returns:

a new Validator instance composing this Validator with the given Validators.

containsId

public boolean containsId(String id)

Parameters:

id - the ID of the Validator to check for.

Returns:

true if this Validator itself has the given ID or recursively contains such Validator, false otherwise.

getChild

public <T> T getChild(Class<T> validatorClass)

Type Parameters:

T - type of the requested Validator.

Parameters:

validatorClass - the Class reflecting the requested Validator.

Returns:

the requested Validator or null if this validator is not of the given type and does not contain any child (recursively) of the given type.

getRange

public <T extends Comparable<?>> Range<T> getRange()

Type Parameters:

T - type of the Range value. Typically of type <V> but e.g. for String or Collection the type would be Integer to validate the size of the actual value.

Returns:

the Range constraint with an optional mimimum and/or maximum value. Will be Range.unbounded() by if no bounds are validated.

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractValidator<V>

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractValidator<V>
