20  * Alternative to the Guice {@link com.google.inject.Provider} that throws
21  * a checked Exception. Users may not inject {@code T} directly.
22  *
23  * <p>This interface must be extended to use application-specific exception types.
24  * Such subinterfaces may not define new methods:
25  * <pre>
26  * public interface RemoteProvider&lt;T&gt; extends ThrowingProvider&lt;T, RemoteException&gt; { }
27  * </pre>
28  *
29  * <p>When this type is bound using {@link ThrowingProviderBinder}, the value returned
30  * or exception thrown by {@link #get} will be scoped. As a consequence, {@link #get}
31  * will invoked at most once within each scope.

35  * @deprecated use {@link CheckedProvider} instead.
