All Implemented Interfaces:

FieldValidator, ValidationRuleDependend

public final class MinimumFieldLengthValidator

extends AbstractFieldValidator

This validator checks on minimum length. If the type of the value is a String, the string length is checked. If the type of the value is a Number, the actual number is used. E.g. if property minLength is 4, "hello" will pass, but "hi" will fail, and number 5 will pass, but 2 will fail.

Method Detail

isValid

public boolean isValid(org.infohazard.maverick.flow.ControllerContext cctx,
                       FormBeanContext formBeanContext,
                       java.lang.String fieldName,
                       java.lang.Object value)

Checks whether the provided value is greater than the minimum. In case the value is an instance of string: checks whether the length of the string is equal to or smaller than the minLength property. In case the value is an instance of number: checks whether the length of the integer value is equal to or smaller than the minLength property.

Parameters:

cctx - maverick context

formBeanContext - context with bean for this currentRequest

fieldName - field name of parameter

value - the value of this parameter

Returns:

boolean true if the length of value is equal to or less than the minLength property, false otherwise
