Method Detail

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