Examples with ParameterNameProvider javax.validation.ParameterNameProvider used on opensource projects

Example 1 with ParameterNameProvider

use of javax.validation.ParameterNameProvider in project spring-framework by spring-projects.

the class LocalValidatorFactoryBean method configureParameterNameProviderIfPossible.

private void configureParameterNameProviderIfPossible(Configuration<?> configuration) {
    // TODO: inner class
    final ParameterNameDiscoverer discoverer = this.parameterNameDiscoverer;
    final ParameterNameProvider defaultProvider = configuration.getDefaultParameterNameProvider();
    configuration.parameterNameProvider(new ParameterNameProvider() {

        @Override
        public List<String> getParameterNames(Constructor<?> constructor) {
            String[] paramNames = discoverer.getParameterNames(constructor);
            return (paramNames != null ? Arrays.asList(paramNames) : defaultProvider.getParameterNames(constructor));
        }

        @Override
        public List<String> getParameterNames(Method method) {
