↳ | com.google.inject.Key<T> |
Binding key consisting of an injection type and an optional annotation. Matches the type and annotation at a point of injection.
For example, Key.get(Service.class, Transactional.class)
will
match:
@Inject public void setService(@Transactional Service service) { ... }
Key
supports generic types via subclassing just like TypeLiteral
.
Keys do not differentiate between primitive types (int, char, etc.) and their correpsonding wrapper types (Integer, Character, etc.). Primitive types will be replaced with their wrapper types when keys are created.

Constructs a new key. Derives the type from this class's type parameter.
Clients create an empty anonymous subclass. Doing so embeds the type parameter in the anonymous class's type hierarchy so we can reconstitute it at runtime despite erasure.
Example usage for a binding of type Foo
annotated with
@Bar
:
new Key<Foo>(Bar.class) {
}.
