NAME

       Sub::HandlesVia::Manual::WithObjectPad - using Sub::HandlesVia with Object::Pad

SYNOPSIS

        use Object::Pad;

        class Kitchen {
          has @foods;
          use Sub::HandlesVia::Declare '@foods', Array => (
            all_foods => 'all',
            add_food  => 'push',
          );
        }

MANUAL

       Sub::HandlesVia allows you to delegate methods from your class to the values of your
       objects' attributes.

       Conceptually, it allows you to define "$object->push_number($n)" to be a shortcut for
       "$object->numbers->push($n)" except that "$object->numbers" is an arrayref, so doesn't
       have methods you can call on it like "push".

       Experimental Object::Pad support is provided by Sub::HandlesVia, including for array and
       hash fields.

       Object::Pad classes are "sealed" after compile time, preventing new methods from being
       installed at run-time. (It's actually trivially easy to add them at runtime, but not using
       the API provided by the Object::Pad MOP, so we don't do that.) This is why
       Sub::Handles::Declare is used, as it creates delegated methods at compile-time.

       The first argument is the field name, including its sigil.

       The second argument is the handler library. If the field name begins with a '@' or '%',
       this is implied to be "Array"/"Hash".

        use Object::Pad;

        class Kitchen {
          has @foods;
          use Sub::HandlesVia::Declare '@foods', (
            all_foods => 'all',
            add_food  => 'push',
          );
        }

       The third argument is a hash of methods to delegate.

   Which Methods Can Be Delegated To?
       The second parameter ("Array" in the synopsis) indicates which library of methods should
       be available. Valid values include Array, Blessed, Bool, Code, Counter, Hash, Number,
       Scalar, and String.

       An arrayref can be provided, though many of the options are conceptually contradictory.

        use Sub::HandlesVia::Declare 'num', [ 'Number', 'Scalar' ] => (
          ...,
        );
