Thanks very much, Nate. Have to admit, however, that I don't really get how
to apply that to my case.
Asssuming, I;ve got these classes:
public interface IFoo {
void setBar(String pValue;
String getBar();
}
public class FooImpl implements IFoo {
private String bar; // Setter and Getter for bar
}
And my Module contains, in particular:
binder.bind(IFoo.class).to(FooImpl.class).in(Scopes.SINGLETON);
How would I ensure that my singleton contains a particular value for "bar"?
