Interface TraversableResolver

All Known Implementing Classes:

DefaultTraversableResolver, HibernateTraversableResolver, JPATraversableResolver, SingleThreadCachedTraversableResolver

public interface TraversableResolver

Contract determining if a property can be accessed by the Bean Validation provider. This contract is called for each property that is being either validated or cascaded. A traversable resolver implementation must be thread-safe.

Method Summary

Methods

Modifier and Type	Method and Description
boolean	isCascadable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) Determine if the Bean Validation provider is allowed to cascade validation on the bean instance returned by the property value marked as @Valid.
boolean	isReachable(Object traversableObject, Path.Node traversableProperty, Class<?> rootBeanType, Path pathToTraversableObject, ElementType elementType) Determine if the Bean Validation provider is allowed to reach the property state

Method Detail

isReachable

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

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

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

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

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

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.
