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

max [INT]
    Get or set the maximum acceptable value. If the field's internal_value() is greater than this value, then the validate() method will return false. If undefined, then no limit on the maximum value is enforced.

min [INT]
    Get or set the minimum acceptable value. If the field's internal_value() is less than this value, then the validate() method will return false. If undefined, then no limit on the minimum value is enforced.

negative [BOOL]
    If BOOL is true or omitted, sets max to 0. If BOOL is false, sets max to undef.

positive [BOOL]
    If BOOL is true or omitted, sets min to 0. If BOOL is false, sets min to undef.
