isLogged in one Controller?

[eluser]FREEZA[/eluser]
Hello.

Ich want to create a Controller called Product. There you can find two methods:

Code:

createProduct(); // This method is only available for users witch are logged in
getAllProducts();// This method is available for all

I read that i could define a isLogged() method in the __Constructor of the Controller Product but then you must be logged in for all methods!

The method getAllProducts() should be available for all!

Please Help me: )
