Annotation Type Numeric

@Retention(CLASS) @Target(FIELD) public @interface Numeric

Requires the component value to parse as a number, optionally within a closed range. The processor emits com.codename1.ui.validation.NumericConstraint(decimal, min, max, message) into the Validator returned by Binding#getValidator().

@Bind(name="ageField") @Numeric(min = 0, max = 150)
private int age;

@Bind(name="priceField") @Numeric(decimal = true, min = 0.01)
private double price;

Bounds are inclusive. Omitting min / max removes that side of the range (the defaults are negative / positive infinity).
