interface Used to declare a special type of class that only
contains abstract methods, constant ( static final ) fields
and static interfaces. It can later be implemented by
classes that declare the interface with the implements
keyword
http://en.wikipedia.org/wiki/Java_keywords
Class verifier from JDK 1.2 beta 4 also makes it impossible
for JavaGO to inline constructors and replace virtual calls
with non-virtual.JavaGO has special options -not-inline-
constructor and -not-use-invokespecial to disable such
optimizations.Option -not-inline-virtual prevents JavaGO
from inlining virtual methods (while it can still inline
final and static methods)and in conjunction with -not-use-
invokespecial option makesoptimization performed by JavaGO
really safe (such classes can be used with other classes
not presented to JavaGO), but looks like such
optimizationsalso can be done by Java compiler with -O
option.
