Mixin redirectors

introduction

Redirectors are methods that can replace method invocations, field accesses, object creation, and instanceof checks. Redirectors are declared by @Redirect annotations and generally look like this: 

  1. @Redirect(method = "${signatureOfMethodInWhichToRedirect}",
  2.           at = @At(value = "${injectionPointReference}", target = "${signature}"))
  3. public ReturnType redirectSomeMethod(Arg0Type arg0, Arg1Type arg1) {
  4.     MyClass.doMyComputations();
  5.  
  6.     return computeSomethingElse();
  7. }
