DESCRIPTION

Rose::HTML::Form::Field::Integer is a subclass of Rose::HTML::Form::Field::Numeric that only accepts integer values. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid integer, or setting an error message and returning false otherwise.

Use the min and :<max|/max> attributes to control whether the range of valid values.

OBJECT METHODS

<B>max [INT]B> Get or set the maximum acceptable value. If the field’s internal_value() is <B>greater thanB> this value, then the validate() method will return false. If undefined, then no limit on the maximum value is enforced.
<B>min [INT]B> Get or set the minimum acceptable value. If the field’s internal_value() is <B>less thanB> this value, then the validate() method will return false. If undefined, then no limit on the minimum value is enforced.
<B>negative [BOOL]B> If BOOL is true or omitted, sets max to 0. If BOOL is false, sets max to undef.
<B>positive [BOOL]B> If BOOL is true or omitted, sets min to 0. If BOOL is false, sets min to undef.
