Method Summary
 boolean isCascadable(java.lang.Object traversableObject, Path.Node traversableProperty, java.lang.Class<?> rootBeanType, Path pathToTraversableObject, java.lang.annotation.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(java.lang.Object traversableObject, Path.Node traversableProperty, java.lang.Class<?> rootBeanType, Path pathToTraversableObject, java.lang.annotation.ElementType elementType)
          Determine if the Bean Validation provider is allowed to reach the property state
 

Method Detail

isReachable

boolean isReachable(java.lang.Object traversableObject,
                    Path.Node traversableProperty,
                    java.lang.Class<?> rootBeanType,
                    Path pathToTraversableObject,
                    java.lang.annotation.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(java.lang.Object traversableObject,
                     Path.Node traversableProperty,
                     java.lang.Class<?> rootBeanType,
                     Path pathToTraversableObject,
                     java.lang.annotation.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.
