11.10. Where We Are So Far...So far, we've used the method arrow syntax: Class->method(@args); or the equivalent: my $beast = 'Class'; $beast->method(@args); which constructs an argument list of: ('Class', @args) and attempts to invoke: Class::method('Class', @args); However, if Perl doesn't find Class::method, it examines @Class::ISA (recursively) to locate a package that does indeed contain method and then invokes that version instead. Chapter 12 shows how to distinguish the individual animals by giving them associated properties, called instance variables. |
