All Implemented Interfaces:
BindingTargetVisitor<T,V>
public abstract class DefaultBindingTargetVisitor<T,V> extends Object implements BindingTargetVisitor<T,V>

    • visitOther

      protected V visitOther(Binding<? extends T> binding)
      Default visit implementation. Returns null.

    • visit

      public V visit(InstanceBinding<? extends T> instanceBinding)
      Description copied from interface: BindingTargetVisitor
      Visit a instance binding. The same instance is returned for every injection. This target is found in both module and injector bindings.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ProviderInstanceBinding<? extends T> providerInstanceBinding)
      Description copied from interface: BindingTargetVisitor
      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.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ProviderKeyBinding<? extends T> providerKeyBinding)
      Description copied from interface: BindingTargetVisitor
      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.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(LinkedKeyBinding<? extends T> linkedKeyBinding)
      Description copied from interface: BindingTargetVisitor
      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.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ExposedBinding<? extends T> exposedBinding)
      Description copied from interface: BindingTargetVisitor
      Visit a binding to a key exposed from an enclosed private environment. This target is only found in injector bindings.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(UntargettedBinding<? extends T> untargettedBinding)
      Description copied from interface: BindingTargetVisitor
      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.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ConstructorBinding<? extends T> constructorBinding)
      Description copied from interface: BindingTargetVisitor
      Visit a constructor binding. To resolve injections, an instance is instantiated by invoking constructor. This target is found only on injector bindings.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ConvertedConstantBinding<? extends T> convertedConstantBinding)
      Description copied from interface: BindingTargetVisitor
      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.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>

    • visit

      public V visit(ProviderBinding<? extends T> providerBinding)
      Description copied from interface: BindingTargetVisitor
      Visit a binding to a Provider that delegates to the binding for the provided type. This target is found only on injector bindings.
      Specified by:
      visit in interface BindingTargetVisitor<T,V>
