Method Detail

getDependency

public Dependency<?> getDependency()

Returns the Dependency, if one exists. For anything that can be referenced by Injector.getBinding(com.google.inject.Key<T>), a dependency exists. A dependency will not exist (and this will return null) for types initialized with Binder.requestInjection(com.google.inject.TypeLiteral<T>, T) or Injector.injectMembers(Object), nor will it exist for objects injected into Providers bound with LinkedBindingBuilder#toProvider(Provider).

getBindingSource

public java.lang.String getBindingSource()

Returns a string describing where this dependency was bound. If the binding was just-in-time, there is no valid binding source, so this describes the class in question.

toString

public java.lang.String toString()

Overrides:
