pack-priv Class CachingJPATraversableResolverForSingleValidation

extends Object
implements TraversableResolver
Class Inheritance
All Implemented Interfaces
jakarta.validation.TraversableResolver
Imports
java.lang.annotation.ElementType, java.util.HashMap, jakarta.validation.Path, .TraversableResolver
Cache results of a delegated JPATraversableResolver to optimize calls.

It should only be used to wrap a JPATraversableResolver as it relies on the contract defined in the Bean Validation specification.

It works only for a single validate* call and should not be used if TraversableResolver is accessed concurrently.

Implements jakarta.validation.TraversableResolver.isCascadable.

Doc from jakarta.validation.TraversableResolver.isCascadable.

Determines if the Jakarta 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, jakarta.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

object hosting traversableProperty or null if validateValue is called

traversableProperty:Path.Node

the traversable property

rootBeanType:Class<?>

type of the root object passed to the Validator or hosting the method or constructor validated

pathToTraversableObject:Path

path from the root object to traversableObject (using the path specification defined by Bean Validation)

elementType:ElementType

either FIELD or METHOD

Returns:boolean

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