====== 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:

<code java [enable_line_numbers=true]>
@Redirect(method = "${signatureOfMethodInWhichToRedirect}",
          at = @At(value = "${injectionPointReference}", target = "${signature}"))
public ReturnType redirectSomeMethod(Arg0Type arg0, Arg1Type arg1) {
    MyClass.doMyComputations();
  
    return computeSomethingElse();
}
</code>
