Declare::Constraints::Simple::Library::Array - Array Constraints
# 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) );
This module contains all constraints that can be applied to array references.
With $min defaulting to 1. So a specification of
$min
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);
Applies the the $constraints to the corresponding $keys if they are present. For required keys see HasArraySize.
$constraint
$key
HasArraySize
Runs the constraint on all even elements of an array. See also OnOddElements.
OnOddElements
Runs the constraint on all odd elements of an array. See also OnEvenElements.
OnEvenElements
