public class LwSpinValidator

extends BasicMaskValidator

This class is a special mask handler that is used by the spin component to validate and represent bound integer value. On the one hand it handles spin masked text field input and on the other hand it defines mask that should be used by the mask validator, converts the integer spin value to the mask value and converts the mask value to the spin integer value.
