Method Detail

validateParameters

<T> Set<ConstraintViolation<T>> validateParameters(T object,
                                                   Method method,
                                                   Object[] parameterValues,
                                                   Class<?>... groups)

Validates all constraints placed on the parameters of the given method.

Type Parameters:

T - the type hosting the method to validate

Parameters:

object - the object on which the method to validate is invoked

method - the method for which the parameter constraints is validated

parameterValues - the values provided by the caller for the given method's parameters

groups - the group or list of groups targeted for validation (defaults to Default)

Returns:

a set with the constraint violations caused by this validation; will be empty if no error occurs, but never null

Throws:

IllegalArgumentException - if null is passed for any of the parameters or if parameters don't match with each other

ValidationException - if a non recoverable error happens during the validation process

validateReturnValue

<T> Set<ConstraintViolation<T>> validateReturnValue(T object,
                                                    Method method,
                                                    Object returnValue,
                                                    Class<?>... groups)

Validates all return value constraints of the given method.

Type Parameters:

T - the type hosting the method to validate

Parameters:

object - the object on which the method to validate is invoked

method - the method for which the return value constraints is validated

returnValue - the value returned by the given method

groups - the group or list of groups targeted for validation (defaults to Default)

Returns:

a set with the constraint violations caused by this validation; will be empty if no error occurs, but never null

Throws:

IllegalArgumentException - if null is passed for any of the object, method or groups parameters or if parameters don't match with each other

ValidationException - if a non recoverable error happens during the validation process

validateConstructorParameters

<T> Set<ConstraintViolation<T>> validateConstructorParameters(Constructor<? extends T> constructor,
                                                              Object[] parameterValues,
                                                              Class<?>... groups)

Validates all constraints placed on the parameters of the given constructor.

Type Parameters:

T - the type hosting the constructor to validate

Parameters:

constructor - the constructor for which the parameter constraints is validated

parameterValues - the values provided by the caller for the given constructor's parameters

groups - the group or list of groups targeted for validation (defaults to Default)

Returns:

a set with the constraint violations caused by this validation; Will be empty if no error occurs, but never null

Throws:

IllegalArgumentException - if null is passed for any of the parameters or if parameters don't match with each other

ValidationException - if a non recoverable error happens during the validation process

validateConstructorReturnValue

<T> Set<ConstraintViolation<T>> validateConstructorReturnValue(Constructor<? extends T> constructor,
                                                               T createdObject,
                                                               Class<?>... groups)

Validates all return value constraints of the given constructor.

Type Parameters:

T - the type hosting the constructor to validate

Parameters:

constructor - the constructor for which the return value constraints is validated

createdObject - the object instantiated by the given method

groups - the group or list of groups targeted for validation (defaults to Default)

Returns:

a set with the constraint violations caused by this validation; will be empty, if no error occurs, but never null

Throws:

IllegalArgumentException - if null is passed for any of the parameters or if parameters don't match with each other

ValidationException - if a non recoverable error happens during the validation process
