Example 1 with MethodInvocation

the class Functionizer method determineFunctionizableMethods.

   * Determines the set of methods to functionize. In addition to a method being
   * final we must also find an invocation for that method. Static methods, though,
   * are always functionized since there are no dynamic dispatch issues.
