Dependency Inversion Principle and Hollywood analogy

Often DIP is known as the Hollywood principle: "Don't call us, we'll call you.".

But doesn't always higher level module calls lower level module, whether there is dependency inversion or not?

Then why is DIP called the Hollywood principle?

Am I missing something? Thanks!

Dependency Inversion Principle - Where should the interfaces go?
8/1/2015 9:40 pm by SnuggleTheBear in Programming Languages

I've been scratching my head about this for a few months and I've still been able to satisfactorily convince myself that I have the right answer. We have a, very typical, situation where we have dependencies between multiple layers of our application where each layer is in its own assembly. As


Dependency Inversion Principle Dilemma
by CjK in Programming Languages
Hi,
According to Robert Martins Dependency Inversion Principle,
http://www.objectmentor.com/resources/articles/dip.pdf,
when there is a need to test the type of an object, the
code inside the "switch cases" should be placed into the
parent class.
However, I a

Isn't Command Pattern an implementation of Dependency Inversion Principle?
by Dennizzz in Programming Languages

Command pattern has three main components: the Invoker, the Command and the Receiver. Client provides the Invoker with information required to call a particular method M on a Receiver, while it is Command object ( which is housed by Receiver ) that actually calls M.


How does dependency inversion principle work in languages without interfaces?
by foghorn67 in Programming Languages
In C#/Java, the dependency inversion principle is often demonstrated by high-level classes that depends on an interface/abstraction (that it owns). Low-level classes will implement the interface, thus inverting the dependency.I wonder, how is it applied in object-oriented languages with no interface
Making this class comply with the Dependency Inversion principle
by Eric in Programming Languages

The definition of DI quoted from Wikipedia states:


A. High-level modules should not depend on low-level modules. Both should depend on abstractions.
B. Abstractions should not depend upon details. Details should depend upon abstractions.
