multiple array parameters to object methods?

[en2guy]

Hi-

trying to understand object oriented perl, and have been wondering
about passing arrays as parameters to object methods.

If I pass a single array as a method parameter, it's fine, eg

$object->raiseFlags(@flags);

However, if I wanted to pass 2 arrays to an object method, I would have
to use references to objects, I think, since

$object->raiseFlags(@flags, @specialOccasions);

would append @specialOccasions to @flags to make a big jumbled list.

Are there any issues to using references as method parameters when
using objects in perl? Is there a better way to approach the problem?

Thanks

Not to objects, necessarily, but array refs are the standard way
of handing in more than one array to a perl sub. Whether the sub
is a method or not is irrelevant.

$object->raiseFlags(@flags, @specialOccasions);

would append @specialOccasions to @flags to make a big jumbled list.

No.

Other ways, yes. Better, no.
