<h2>Class Overview</h2>
<p>An object capable of providing instances of type <code>T</code>. Providers are used in numerous ways
by Guice:
<ul>
<li>When the default means for obtaining instances (an injectable or parameterless constructor)
is insufficient for a particular binding, the module can specify a custom <code>Provider</code>
instead, to control exactly how Guice creates or obtains instances for the binding.
<li>An implementation class may always choose to have a <code>Provider&lt;T&gt;</code> instance injected,
rather than having a <code>T</code> injected directly. This may give you access to multiple
instances, instances you wish to safely mutate and discard, instances which are out of scope
(e.g. using a <code>@RequestScoped</code> object from within a <code>@SessionScoped</code> object), or
instances that will be initialized lazily.
<li>A custom <code><a href="../../../com/google/inject/Scope.html">Scope</a></code> is implemented as a decorator of <code>Provider&lt;T&gt;</code>, which decides
when to delegate to the backing provider and when to provide the instance some other way.
<li>The <code><a href="../../../com/google/inject/Injector.html">Injector</a></code> offers access to the <code>Provider&lt;T&gt;</code> it uses to fulfill requests
for a given key, via the <code><a href="../../../com/google/inject/Injector.html#getProvider(com.google.inject.Key<T>)">getProvider(Key<T>)</a></code> methods.
