Add hooks on methods from other classes
ClassHook enables you to trace methods calls from your code to other classes.
Instead of putting ‘use Foo;’ in your code, simply type ‘use ClassHook;’. The class Foo is unknown in your code. It will be magically caught by ClassHook which will call Foo itself. You can see ClassHook as a kind of relay.
You can setup a subroutine to be called before any call to Foo->amethod and a subroutine to be called after the call. Your subs will receive all the information that Foo->amethod will receive, so you can trace everything between your code and Foo.
