Declare::Constraints::Simple::Library::Array - Array Constraints

       Robert 'phaylon' Sedlacek "<phaylon@dunkelheit.at>"

HasArraySize([$min,[$max]])
       With $min defaulting to 1. So a specification of

         my $profile = HasArraySize;

       checks for at least one value. To force an exact size of the array, specify the same values for both:

         my $profile = HasArraySize(3, 3);

   OnArrayElements($key=>$constraint,$key=>$constraint,...)
       Applies the the $constraints to the corresponding $keys if they are present. For required keys see
       "HasArraySize".

   OnEvenElements($constraint)
       Runs the constraint on all even elements of an array. See also "OnOddElements".

   OnOddElements($constraint)
       Runs the constraint on all odd elements of an array. See also "OnEvenElements".
