In case you really need to inject value classes, Guice does that for you for free. If you @Inject a Person (non-scoped), every time will give a new Person.
But I can't figure out why a simple value class should be managed by Guice. In this case I'm sure that's easier and clearer to just use a regular, old-fashioned new. If what you're looking for is to inject a Service in conjunction with some value class, take a look at Assisted Inject [1] hth, jordi [1] http://code.google.com/p/google-guice/wiki/AssistedInject On Thu, May 10, 2012 at 10:45 PM, Bubba 42 <bubba424...@gmail.com> wrote: > Hi, > > I've been unable to find a suitable answer to this question. > > If I understand this correctly: Dependency Injection can be used to > instantiate service objects -- object that essentially abstract away > some computational service ... for example (an instance of this class > would essentially be stateless, save for resources that it might be > plugged into such as SimpleMath.properties, and I would expect that > there would be small number of instances of this class per application > instance say under 5): > > class SimpleMath { > > public int addTwoNumbers (int n1, int n2) { > return n1 + n2; > } > > public int multiplyTwoNumbers (int n1, int n2) { > return n1 * n2; > } > > } > > Now can DI be used to instantiate value objects (for the lack of a > better word).
