Method Detail

visitEagerSingleton

V visitEagerSingleton()

Visit an eager singleton or single instance. This scope strategy is found on both module and injector bindings.

visitScope

V visitScope(Scope scope)

Visit a scope instance. This scope strategy is found on both module and injector bindings.

visitScopeAnnotation

V visitScopeAnnotation(Class<? extends Annotation> scopeAnnotation)

Visit a scope annotation. This scope strategy is found only on module bindings. The instance that implements this scope is registered by Binder.bindScope().

visitNoScoping

V visitNoScoping()

Visit an unspecified or unscoped strategy. On a module, this strategy indicates that the injector should use scoping annotations to find a scope. On an injector, it indicates that no scope is applied to the binding. An unscoped binding will behave like a scoped one when it is linked to a scoped binding.
