 sample.evolve.Evolution
| Evolution | | public class Evolution implements Translator(Code) | | Evolution provides a set of methods for instrumenting bytecodes.
For class evolution, updatable class A is renamed to B. Then an abstract
class named A is produced as the super class of B. If the original class A
has a public method m(), then the abstract class A has an abstract method
m().
abstract class A abstract m() _makeInstance() | class A --------> class B m()
m()
Also, all the other classes are translated so that "new A(i)" in the methods
is replaced with "_makeInstance(i)". This makes it possible to change the
behavior of the instantiation of the class A.
