NAME
Rose::HTML::Form::Field::Email - Text field that only accepts valid email addresses.
SYNOPSIS
$field =
Rose::HTML::Form::Field::Email->new(
label => 'Email',
name => 'email',
size => 30,
maxlength => 255);
if($field->validate)
{
$email = $field->internal_value;
}

}
print $field->html;
...DESCRIPTION
Rose::HTML::Form::Field::Email is a subclass of Rose::HTML::Form::Field::Text that uses Email::Valid to allow only valid email addresses as input. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid email address, or setting an error message and returning false otherwise.
This is a good example of a custom field class that simply constrains the kinds of inputs that it accepts, but does not inflate/deflate values or aggregate other fields.
