* Package name : libclass-isa-perl Version : 0.36 Upstream Author : Sean M. Burke <[email protected]> * URL : http://search.cpan.org/dist/Class-ISA/ * License : Perl Programming Lang: Perl Description : report the search path for a class's ISA tree Suppose you have a class (like Food::Fish::Fishstick) that is derived, via its @ISA, from one or more superclasses (as Food::Fish::Fishstick is from Food::Fish, Life::Fungus, and Chemicals), and some of those superclasses may themselves each be derived, via its @ISA, from one or more superclasses (as above). When, then, you call a method in that class ($fishstick->calories), Perl first searches there for that method, but if it's not there, it goes searching in its superclasses, and so on, in a depth-first (or maybe "height-first" is the word) search. In the above example, it'd first look in Food::Fish, then Food, then Matter, then Life::Fungus, then Life, then Chemicals. This library, Class::ISA, provides functions that return that list -- the list (in order) of names of classes Perl would search to find a method, with no duplicates. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
