    • Method Detail

      • isReachable

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

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

        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
