Class LengthValidator

java.lang.Object
  extended by javax.faces.validator.LengthValidator
All Implemented Interfaces:
EventListener, PartialStateHolder, StateHolder, Validator

@JSFValidator(name="f:validateLength",
              bodyContent="empty",
              tagClass="org.apache.myfaces.taglib.core.ValidateLengthTag")
@JSFJspProperty(name="binding",
                returnType="javax.faces.validator.LengthValidator",
                longDesc="A ValueExpression that evaluates to a LengthValidator.")
public class LengthValidator
extends Object
implements Validator, PartialStateHolder

Creates a validator and associateds it with the nearest parent UIComponent. When invoked, the validator ensures that values are valid strings with a length that lies within the minimum and maximum values specified. Commonly associated with a h:inputText entity. Unless otherwise specified, all attributes accept static values or EL expressions. see Javadoc of JSF Specification
