I suspect that what you want is documentation, because a literal answer
to your question will only give a list of method names, which is rarely
useful (I've used it on occasion for very specialized classes where that
list constituted metadata of a sort.)
As Lesley said, if you don't find the methods you're looking for in the
class itself, try superclasses. This is one case where the structured
nature of documentation in more rigid languages has an edge over Perl.
