Certain applications like to defer the decision to use a particular module
|
|
till runtime. This is possible in perl, and is a useful trick in situations
|
|
where the type of data is not known at compile time and the application
|
|
doesn't wish to pre-compile modules to handle all types of data it can work
|
|
with. Loading modules at runtime can also provide flexible interfaces for
|
|
perl modules. Modules can let the programmer decide what modules will be
|
|
used by it instead of hard-coding their names.
|
|
|
|
Class::Loader is an inheritable class that provides a method, _load(), to
|
|
load a module from disk and construct an object by calling its constructor.
|
|
It also provides a way to map modules names and associated metadata with
|
|
symbolic names that can be used in place of module names at _load().
