/**
* Collects configuration information (primarily <i>bindings</i>) which will be
* used to create an {@link Injector}. Guice provides this object to your
* application's {@link Module} implementors so they may each contribute
* their own bindings and other registrations.
*
* <h3>The Guice Binding EDSL</h3>
*
* Guice uses an <i>embedded domain-specific language</i>, or EDSL, to help you
* create bindings simply and readably. This approach is great for overall
* usability, but it does come with a small cost: <b>it is difficult to
* learn how to use the Binding EDSL in the usual way -- by reading
* method-level javadocs</b>. Instead, you should consult this series of
* examples below. To save space, these examples omit the opening
* {@code binder.}, just as you will if your module extends
* {@link AbstractModule}.
*
* <pre>
* bind(ServiceImpl.class);</pre>
*
* This statement does essentially nothing; it "binds the {@code ServiceImpl}
* class to itself" and does not change Guice's default behavior. You may still
* want to use this if you prefer your {@link Module} class to serve as an
* explicit <i>manifest</i> for the services it provides. Also, in rare cases,
* Guice may be unable to validate a binding at injector creation time unless it
* is given explicitly.
*
* <pre>
* bind(Service.class).to(ServiceImpl.class);</pre>
*
* Specifies that a request for a {@code Service} instance with no binding
* annotations should be treated as if it were a request for a
* {@code ServiceImpl} instance. This <i>overrides</i> the function of any
* {@link ImplementedBy @ImplementedBy} or {@link ProvidedBy @ProvidedBy}
* annotations found on {@code Service}, since Guice will have already
* "moved on" to {@code ServiceImpl} before it reaches the point when it starts
* looking for these annotations.
*
* <pre>
* bind(Service.class).toProvider(ServiceProvider.class);</pre>
*
* In this example, {@code ServiceProvider} must extend or implement
* {@code Provider<Service>}. This binding specifies that Guice should resolve
* an unannotated injection request for {@code Service} by first resolving an
* instance of {@code ServiceProvider} in the regular way, then calling
* {@link Provider#get get()} on the resulting Provider instance to obtain the
* {@code Service} instance.
*
* <p>The {@link Provider} you use here does not have to be a "factory"; that
* is, a provider which always <i>creates</i> each instance it provides.
* However, this is generally a good practice to follow. You can then use
* Guice's concept of {@link Scope scopes} to guide when creation should happen
* -- "letting Guice work for you".
*
* <pre>
* bind(Service.class).annotatedWith(Red.class).to(ServiceImpl.class);</pre>
*
* Like the previous example, but only applies to injection requests that use
* the binding annotation {@code @Red}. If your module also includes bindings
* for particular <i>values</i> of the {@code @Red} annotation (see below),
* then this binding will serve as a "catch-all" for any values of {@code @Red}
* that have no exact match in the bindings.
*
* <pre>
* bind(ServiceImpl.class).in(Singleton.class);
* // or, alternatively
* bind(ServiceImpl.class).in(Scopes.SINGLETON);</pre>
*
* Either of these statements places the {@code ServiceImpl} class into
* singleton scope. Guice will create only one instance of {@code ServiceImpl}
* and will reuse it for all injection requests of this type. Note that it is
* still possible to bind another instance of {@code ServiceImpl} if the second
* binding is qualified by an annotation as in the previous example. Guice is
* not overly concerned with <i>preventing</i> you from creating multiple
* instances of your "singletons", only with <i>enabling</i> your application to
* share only one instance if that's all you tell Guice you need.
*
* <p><b>Note:</b> a scope specified in this way <i>overrides</i> any scope that
* was specified with an annotation on the {@code ServiceImpl} class.
*
* <p>Besides {@link Singleton}/{@link Scopes#SINGLETON}, there are
* servlet-specific scopes available in
* {@code com.google.inject.servlet.ServletScopes}, and your Modules can
* contribute their own custom scopes for use here as well.
*
* <pre>
* bind(new TypeLiteral<PaymentService<CreditCard>>() {})
* .to(CreditCardPaymentService.class);</pre>
*
* This admittedly odd construct is the way to bind a parameterized type. It
* tells Guice how to honor an injection request for an element of type
* {@code PaymentService<CreditCard>}. The class
* {@code CreditCardPaymentService} must implement the
* {@code PaymentService<CreditCard>} interface. Guice cannot currently bind or
* inject a generic type, such as {@code Set<E>}; all type parameters must be
* fully specified.
*
* <pre>
* bind(Service.class).toInstance(new ServiceImpl());
* // or, alternatively
* bind(Service.class).toInstance(SomeLegacyRegistry.getService());</pre>
*
* In this example, your module itself, <i>not Guice</i>, takes responsibility
* for obtaining a {@code ServiceImpl} instance, then asks Guice to always use
* this single instance to fulfill all {@code Service} injection requests. When
* the {@link Injector} is first created, it will automatically perform field
* and method injection for this instance, but any injectable constructor on
* {@code ServiceImpl} is simply ignored. Note that using this approach results
* in "eager loading" behavior that you can't control.
*
* <pre>
* bindConstant().annotatedWith(ServerHost.class).to(args[0]);</pre>
*
* Sets up a constant binding. Constant bindings are typeless in Guice; you
* can provide the values in a variety of types and the values can be injected
* in a variety of types; Guice performs the standard type conversions for you
* behind the scenes. Because of this "typelessness", constant injections must
* always be annotated.
*
* <pre>
* {@literal @}Color("red") Color red; // A member variable (field)
* . . .
* red = MyModule.class.getField("red").getAnnotation(Color.class);
* bind(Service.class).annotatedWith(red).to(RedService.class);</pre>
*
* If your binding annotation has parameters you can apply different bindings to
* different specific values of your annotation. Getting your hands on the
* right instance of the annotation is a bit of a pain -- one approach, shown
* above, is to apply a prototype annotation to a field in your module class, so
* that you can read this annotation instance and give it to Guice.
*
* <pre>
* bind(Service.class)
* .annotatedWith(Names.named("blue"))
* .to(BlueService.class);</pre>
*
* Differentiating by names is a common enough use case that we provided a
* standard annotation, {@link com.google.inject.name.Named @Named}. Because of
* Guice's library support, binding by name is quite easier than in the
* arbitrary binding annotation case we just saw. However, remember that these
* names will live in a single flat namespace with all the other names used in
* your application.
*
* <p>The above list of examples is far from exhaustive. If you can think of
* how the concepts of one example might coexist with the concepts from another,
* you can most likely weave the two together. If the two concepts make no
* sense with each other, you most likely won't be able to do it. In a few
* cases Guice will let something bogus slip by, and will then inform you of
* the problems at runtime, as soon as you try to create your Injector.
*
* <p>The other methods of Binder such as {@link #bindScope},
* {@link #bindInterceptor}, {@link #install}, {@link #requestStaticInjection},
* {@link #addError} and {@link #currentStage} are not part of the Binding EDSL;
* you can learn how to use these in the usual way, from the method
* documentation.
