Package org.apache.wicket.validation

Class Validatable<T>

  • Type Parameters:
    T - type of validatable
    All Implemented Interfaces:
    IValidatable<T>
    public class Validatable<T>
extends java.lang.Object
implements IValidatable<T>
    This implementation of IValidatable is meant to be used outside of Wicket. It allows other parts of the application to utilize IValidators for validation.

    Example: 

     class WebService
 {
        public void addUser(String firstName, String lastName)
        {
                Validatable standin = new Validatable();
                standin.setValue(firstName);
                new FirstNameValidator().validate(standin);
                standing.setValue(lastName);
                new LastNameValidator().validate(standin);
                if (!standin.isValid())
                {
                        // roll your own ValidationException
                        throw new ValidationException(standin.getErrors());
                }
                else
                {
                        // add user here
                }
        }
 }
