[hibernate-issues] [Hibernate-JIRA] Commented: (BVAL-36) Validation of method parameters and returned values

Validation of method parameters and returned values --------------------------------------------------- Key: BVAL-36 URL: http://opensource.atlassian.com/projects/hibernate/browse/BVAL-36 Project: Bean Validation Issue Type: New Feature Components: spec-general Reporter: Emmanuel Bernard Assignee: Emmanuel Bernard The goal is to expose the necessary APIs to validate method parameters and returned type. This API can typically be used by an interceptor framework. Validator { List<IC> validateParameters(Method, Object[] parameterValues); List<IC> validateParameter(Method, Object parameterValue, int parameterIndex); List<IC> validateReturnedValue(Method, Object returnedValue); List<IC> validateParameters(Constructor, Object[] parameterValues); List<IC> validateParameter(Constructor, Object parameterValue, int parameterIndex); } Metadata Validator { BeanDescriptor getConstraintsForBean() PropertyDescriptor getConstraintsForProperty(String propertyName); MethodDescriptor getConstraintsForMethod(Method); MethodDescriptor getConstraintsForConstructor(Constructor); String[] getValidatedProperties(); Method[] getValidatedMethods(); Constructor[] getValidatedConstructors(); } ElementDescriptor { ElementType getElementType(); Class getType(); List<ConstraintDescriptor> getConstraintDescriptors(); } PropertyDescriptor extends ElementDescriptor { boolean isCascaded(); String getPropertyPath(); } ParameterDescriptor extends ElementDescriptor { boolean isCascaded(); int getIndex(); } BeanDescriptor extends ElementDescriptor { } MethodDescriptor extends ElementDescriptor { List<ParameterDescriptor> getParameterDescriptors(); //index aligned boolean isCascaded(); } ConstructorDescriptor extends ElementDescriptor { List<ParameterDescriptor> getParameterDescriptors(); //index aligned } How to read parameter annotations Class<?> parameterTypes = method.getParameterTypes() Annotation[][] parameterAnnotations = method.getParameterAnnotations()
