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
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.
Runs the constraint on all even elements of an array. See also
OnOddElements.
Runs the constraint on all odd elements of an array. See also
OnEvenElements.
