Description copied from interface: MethodValidator

Validates a given parameter of a given method.

Specified by:

validateParameter in interface MethodValidator

Type Parameters:

T - The type hosting the invoked method.

Parameters:

object - The object on which the given method was invoked.

method - The invoked method for which the given parameter shall be validated.

parameterValue - The value provided by the caller for the given method.

parameterIndex - The index of the parameter to be validated within the given method's parameter array.

groups - A - potentially empty - number of validation groups for which the validation shall be performed. The @link Default group will be validated if no group is given.

Returns:

A set with the constraint violations caused by this validation. Will be empty, of no error occurs, but never null.

validateAllParameters

public final <T> java.util.Set<MethodConstraintViolation<T>> validateAllParameters(T object,
                                                                                   java.lang.reflect.Method method,
