public final class RealMultibinder<T> extends Object implements Module
As a Multibinder, it acts as a factory for LinkedBindingBuilders for each of the set's elements. Each binding is given an annotation that identifies it as a part of this set.
As a Module, it installs the binding to the set itself. As a module, this implements equals() and hashcode() in order to trick Guice into executing its configure() method only once. That makes it so that multiple multibinders can be created for the same target collection, but only one is bound. Since the list of bindings is retrieved from the injector itself (and not the multibinder), each multibinder has access to all contributions from all multibinders.
As a Provider, this constructs the set instances.
We use a subclass to hide 'implements Module, Provider' from the public API.

Do not invoke this method directly to install submodules. Instead use
Binder.install(Module), which ensures that provider methods are
discovered.
