Method Detail

isReachable

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

Description copied from interface: TraversableResolver

Determines 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 or hosting the method or constructor validated

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

Description copied from interface: TraversableResolver

Determines 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 TraversableResolver.isReachable(Object, javax.validation.Path.Node, Class, Path, java.lang.annotation.ElementType) 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 or hosting the method or constructor validated

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
