Re: [Pharo-dev] reflection examples

by Igor Stasenko

Hmm, given such examples, it makes me doubt, how to properly answer the question 'what is reflection'.. Because when you saying: SomeClass selectors includes: #foo is it using reflection? but looking from plain perspective it is nothing more than accessing properties stored in object, using methods, provided by object.. and not much different to accessing properties of any other object , like: point x so, what kind of access is clearly 'reflective', and what is not?

Does anyone have other examples? Method wrappers in combination with setting of fields in other objects? A simple ad hoc 'framework' to map UI fields by name to object fields? Serialization/Deserialization? Mockup Objects for testing?

Tom, you have to look at the colums "Lundi Ã Dimanche", there's only 2 buses on sunday from the airport, 4 from Train station / Gare routiÃ¨res (you can go from airport to train station using local buses). Maybe you can team with someone to take a taxi ?
