Class JPATraversableResolver

java.lang.Object

org.hibernate.validator.engine.resolver.JPATraversableResolver

All Implemented Interfaces:

TraversableResolver

public class JPATraversableResolver
extends Object
implements TraversableResolver

An implementation of TraversableResolver which is aware of JPA 2 and utilizes PersistenceUtil to get query the reachability of a property. This resolver will be automatically enabled if JPA 2 is on the classpath and the DefaultTraversableResolver is used.

Method Detail

isReachable

public final boolean isReachable(Object traversableObject,
                  Path.Node traversableProperty,
                  Class<?> rootBeanType,
                  Path pathToTraversableObject,
                  ElementType elementType)

Description copied from interface: TraversableResolver

Determine if the Bean Validation provider is allowed to reach the property state

Specified by:

isReachable in interface TraversableResolver

Parameters:

traversableObject - object hosting traversableProperty or null if validateValue is called

traversableProperty - the traversable property.

rootBeanType - type of the root object passed to the Validator.

pathToTraversableObject - path from the root object to traversableObject (using the path specification defined by Bean Validator).

elementType - either FIELD or METHOD.

Returns:

true if the Bean Validation provider is allowed to reach the property state, false otherwise.

isCascadable

public final boolean isCascadable(Object traversableObject,
                   Path.Node traversableProperty,
                   Class<?> rootBeanType,
                   Path pathToTraversableObject,
                   ElementType elementType)

Description copied from interface: TraversableResolver

Determine if the Bean Validation provider is allowed to cascade validation on the bean instance returned by the property value marked as @Valid. Note that this method is called only if isReachable returns true for the same set of arguments and if the property is marked as @Valid

Specified by:

isCascadable in interface TraversableResolver

Parameters:

traversableObject - object hosting traversableProperty or null if validateValue is called

traversableProperty - the traversable property.

rootBeanType - type of the root object passed to the Validator.

pathToTraversableObject - path from the root object to traversableObject (using the path specification defined by Bean Validator).

elementType - either FIELD or METHOD.

Returns:

true if the Bean Validation provider is allowed to cascade validation, false otherwise.
