  • Method Details

    • 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​(java.lang.Class<? extends java.lang.annotation.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.
