public interface Scope
A scope is a level of visibility that instances provided by Guice may have.
By default, an instance created by the Injector
has no scope,
meaning it has no state from the framework's perspective -- the
Injector
creates it, injects it once into the class that required it,
and then immediately forgets it. Associating a scope with a particular
binding allows the created instance to be "remembered" and possibly used
again for other injections.
An example of a scope is Scopes.SINGLETON
.
