Meaning of { *; } in ProGuard

问题

Consider this proguard statement :

-keep public class * extends android.support.design.widget.CoordinatorLayout$Behavior { *; }

In this statement what does the addition of { *; } mean?

Does it preserve all methods? All fields? Or just the entire class?

回答1:

It is used as a wildcard in ProGuard to indicate all members and methods in the class.
