Deferred binding only occurs when you use GWT.create(). If you "new
ViewFactory()", there's no reason you'll be given a TableViewFactory. GWT
doesn't change Java's semantics.
What you have to do is to use a distinct Ginjector depending on the form
factor, and you can re-use the same GinModule(s) for all the shared binding
configurations, and add a specific GinModule per form factor.
Unfortunately, you cannot use both a generate-with (GIN's Ginjector) and
replace-with (chose the right Ginjector depending on form factor), so
you'll have to use a replace-with rule on a "provider class" for you
Ginjector:
interface MyGinjector extends Ginjector {
// all your accessors
}
@GinModules(SharedGinModule.class, DesktopGinModule.class)
interface DesktopGinjector extends Ginjector {
// nothing special here; it's only used for the @GinModules annotation
}
@GinModules(SharedGinModule.class, TabletGinModule.class)
interface TabletGinjector extends Ginjector { }
@GinModules(SharedGinModule.class, PhoneGinModule.class)
interface PhoneGinjector extends Ginjector { }
interface GinjectorProvider {
MyGinjector get();
}
class DesktopGinjectorProvider implements GinjectorProvider {
public MyGinjector get() { return GWT.create(DesktopGinjector.class); }
}
class TabletGinjectorProvider implements GinjectorProvider {
public MyGinjector get() { return GWT.create(TabletGinjector.class); }
}
class PhoneGinjectorProvider implements GinjectorProvider {
public MyGinjector get() { return GWT.create(PhoneGinjector.class); }
}
<replace-with class="...DesktopGinjectorProvider">
<when-type-is class="...GinjectorProvider" />
<when-property-is name="formfactor" value="desktop" />
</replace-with>
