What is the member variables list after the colon in a constructor good for?

Question

I\'m reading this C++ open source code and I came to a constructor but I don\'t get it ( basically because I don\'t know C++ :P )

I understand C and Java very well.

Answer 1

:: Actually means contains (see comments for clarification), however the _someMethods and so forth is what's called an initialisation list. There is plenty of info at the link =]

EDIT: Sorry, my first sentence is incorrect - see the comments.
