Method Detail
-
get
public static <T> Dependency<T> get(Key<T> key)
Returns a new dependency that is not attached to an injection point. The returned dependency is nullable.
-
forInjectionPoints
public static Set<Dependency<?>> forInjectionPoints(Set<InjectionPoint> injectionPoints)
Returns the dependencies from the given injection points.
-
isNullable
public boolean isNullable()
Returns true if null is a legal value for this dependency.
-
getInjectionPoint
public InjectionPoint getInjectionPoint()
Returns the injection point to which this dependency belongs, or null if this dependency isn't attached to a particular injection point.
-
getParameterIndex
public int getParameterIndex()
Returns the index of this dependency in the injection point's parameter list, or-1if this dependency does not belong to a parameter list. Only method and constuctor dependencies are elements in a parameter list.
