Puppet classes are not executable and cannot be "called". They can be "declared", or the term "included" means about the same thing. Or "assigned", sometimes. > > I know it is possible to call different classes within a module by using > inheritance and using different .pp config files.

Even that's pretty much a hack, but it seems to have gained general acceptance. Laying out your classes and type definitions each in their own manifest (.pp) file, arranged in the way that the autoloader expects them to be, on the other hand, is certainly a big piece of the puzzle. It's not necessary in the strictest sense, but what you're asking is not really practical if you don't. With that said, the bottom line is what Russell said: any class or type definition, in any module, can be referenced from any manifest by its qualified name. Generally, module_name::[inner_namespace:: ...]class_name is sufficient, but for absolute certainty use the absolute form: ::module_name::[inner_namespace:: ...]class_name (note the leading :: ). If you refer to classes or defined types that have not yet been parsed, however, then Puppet must be able to find their definitions based only on their names, which is where the autoloader comes in.
