Module jakarta.validation

Package jakarta.validation.spi

Interface ValidationProvider<T extends Configuration<T>>

Type Parameters:

T - the provider specific Configuration subclass which typically host provider's additional configuration methods

public interface ValidationProvider<T extends Configuration<T>>

Contract between the validation bootstrap mechanism and the provider engine.

Implementations must have a public no-arg constructor. The construction of a provider should be as "lightweight" as possible.

Method Summary

Modifier and Type	Method	Description
ValidatorFactory	buildValidatorFactory(ConfigurationState configurationState)	Build a ValidatorFactory using the current provider implementation.
Configuration<?>	createGenericConfiguration(BootstrapState state)	Returns a Configuration instance.
T	createSpecializedConfiguration(BootstrapState state)	Returns a Configuration instance implementing T, the Configuration sub-interface.

Method Details

createSpecializedConfiguration

T createSpecializedConfiguration(BootstrapState state)

Returns a Configuration instance implementing T, the Configuration sub-interface. The returned Configuration instance must use the current provider (this) to build the ValidatorFactory instance.

Parameters:

state - bootstrap state

Returns:

specific Configuration implementation

createGenericConfiguration

Configuration<?> createGenericConfiguration(BootstrapState state)

Returns a Configuration instance. This instance is not bound to use the current provider. The choice of provider follows the algorithm described in Configuration

The ValidationProviderResolver used by Configuration is provided by state. If null, the default ValidationProviderResolver is used.

Parameters:

state - bootstrap state

Returns:

non specialized Configuration implementation

buildValidatorFactory

ValidatorFactory buildValidatorFactory(ConfigurationState configurationState)

Build a ValidatorFactory using the current provider implementation.

The ValidatorFactory is assembled and follows the configuration passed via ConfigurationState.

The returned ValidatorFactory is properly initialized and ready for use.

Parameters:

configurationState - the configuration descriptor

Returns:

the instantiated ValidatorFactory

Throws:

ValidationException - if the ValidatorFactory cannot be built
