Provides template for a method that invokes an operation on a bean. The method or field that the operation is performed on is chosen by the supplied index and the resulting bytecode uses jump to simulate if/then/else statements The invocation on the bean is configurable via a SinglePropStackManipulationSupplier One possible bytecode outcome would be:

if (var2 == 0) {
     varX.setA(var3);
 } else if (var2 == 1) {
     varX.setB(var3);
 } else {
     varX.setC(var3);
 }

Another possible bytecode outcome this class could produce would be:

if (var2 == 0) {
     return varX.getA();
 } else if (var2 == 1) {
     return varX.getB();
 } else {
     return varX.getC();
 }
