Module io.avaje.validation

Package io.avaje.validation.adapter

Interface ValidationAdapter<T>

Type Parameters:

T - The type of value to be validated

All Known Implementing Classes:

AbstractConstraintAdapter, ContainerAdapter, PrimitiveAdapter

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface ValidationAdapter<T>

This interface defines a set of validation methods for validating a value based on specific rules. The methods in this interface allow for executing validations, composing validation adapters, and checking validation groups.

Method Details

validate

boolean validate(T value,
 ValidationRequest req,
 String propertyName)

Execute validations for the given value.

Parameters:

value - The value to be validated

req - The validation request containing group/locale/violation information

propertyName - The name of the property being validated

Returns:

true if validation should continue, false otherwise

validate

default boolean validate(T value,
 ValidationRequest req)

Execute validations for the given value

Parameters:

value - The value to be validated

req - The validation request containing group/locale/violation information

Returns:

true if validation should continue, false otherwise

primitive

default ValidationAdapter.Primitive primitive()

Return a primitive adapter. Supports int, long with Range, Min, Max, Positive.

list

default ContainerAdapter<T> list()

Create an adapter for validating a list of values.

Returns:

The adapter for list validation

mapKeys

default ContainerAdapter<T> mapKeys()

Create an adapter for validating map keys.

Returns:

The adapter for map key validation

mapValues

default ContainerAdapter<T> mapValues()

Create an adapter for validating map values.

Returns:

The adapter for map value validation

array

default ContainerAdapter<T> array()

Create an adapter for validating an array.

Returns:

The adapter for array validation

optional

default ContainerAdapter<T> optional()

Create an adapter for validating an optional value.

Returns:

The adapter for optional value validation

andThen

default ValidationAdapter<T> andThen(ValidationAdapter<? super T> after)

Compose this validation adapter with another adapter by applying the validations in sequence.

Parameters:

after - The validation adapter to be applied after this adapter

Returns:

The composed validation adapter

Throws:

NullPointerException - if after is null

checkGroups

default boolean checkGroups(Set<Class<?>> adapterGroups,
 ValidationRequest request)

Check if the validation request groups are empty or match any of the adapter's configured groups.

Parameters:

adapterGroups - The groups configured for this adapter

request - The validation request containing the groups to be checked

Returns:

true if the groups match or if the validation request groups are empty, false otherwise
