  • Method Details

    • visit

      V visit(InstanceBinding<? extends T> binding)
      Visit a instance binding. The same instance is returned for every injection. This target is found in both module and injector bindings.

    • visit

      V visit(ProviderInstanceBinding<? extends T> binding)
      Visit a provider instance binding. The provider's get method is invoked to resolve injections. This target is found in both module and injector bindings.

    • visit

      V visit(ProviderKeyBinding<? extends T> binding)
      Visit a provider key binding. To resolve injections, the provider key is first resolved, then that provider's get method is invoked. This target is found in both module and injector bindings.

    • visit

      V visit(LinkedKeyBinding<? extends T> binding)
      Visit a linked key binding. The other key's binding is used to resolve injections. This target is found in both module and injector bindings.

    • visit

      V visit(ExposedBinding<? extends T> binding)
      Visit a binding to a key exposed from an enclosed private environment. This target is only found in injector bindings.

    • visit

      V visit(UntargettedBinding<? extends T> binding)
      Visit an untargetted binding. This target is found only on module bindings. It indicates that the injector should use its implicit binding strategies to resolve injections.

    • visit

      V visit(ConstructorBinding<? extends T> binding)
      Visit a constructor binding. To resolve injections, an instance is instantiated by invoking constructor. This target is found only on injector bindings.

    • visit

      V visit(ConvertedConstantBinding<? extends T> binding)
      Visit a binding created from converting a bound instance to a new type. The source binding has the same binding annotation but a different type. This target is found only on injector bindings.

    • visit

      V visit(ProviderBinding<? extends T> binding)
      Visit a binding to a Provider that delegates to the binding for the provided type. This target is found only on injector bindings.
