SYNOPSIS
# accept a list of pairs
my $pairs_validation = IsArrayRef( HasArraySize(2,2) );
# integer => object pairs
my $pairs = And( OnEvenElements(IsInt),
OnOddElements(IsObject) );
# a three element array
my $tri = And( HasArraySize(3,3),
OnArrayElements(0, IsInt,
1, IsDefined,
2, IsClass) );
DESCRIPTION
This module contains all constraints that can be applied to array
references.
CONSTRAINTS
HasArraySize([$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".
