use of com.google.inject.internal.ProviderMethod in project google-gin by gwtplus.

the class GuiceBindingVisitor method visit.

public Void visit(ProviderInstanceBinding<? extends T> providerInstanceBinding) {
    // Detect provider methods and handle them
    // TODO(bstoler): Update this when the SPI explicitly has a case for
    // provider methods
    Provider<? extends T> provider = providerInstanceBinding.getProviderInstance();
    if (provider instanceof ProviderMethod) {
        Context context = Context.forElement(providerInstanceBinding);
        bindingsCollection.addBinding(targetKey, bindingFactory.getProviderMethodBinding((ProviderMethod<?>) provider, context));
        return null;
    }
    if (provider instanceof GwtDotCreateProvider) {
        addImplicitBinding(providerInstanceBinding);
        return null;

    // OTt, use the normal default handler (and error)
    return super.visit(providerInstanceBinding);
}

Example 7 with ProviderMethod

the class ProviderMethodsTest method testNonModuleProviderMethods.

    Key<String> key = Key.get(String.class, Names.named("foo"));
    assertEquals("foo-value", injector.getInstance(key));
    // Test the provider method object itself. This makes sure getInstance works, since GIN uses it
