      Returns a new dependency that is not attached to an injection point. The returned dependency is nullable.

    • forInjectionPoints

      public static <<InjectionPoint> injectionPoints)
      Returns the dependencies from the given injection points.

    • getKey

      public Key<T> getKey()
      Returns the key to the binding that satisfies this dependency.

    • 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 -1 if this dependency does not belong to a parameter list. Only method and constructor dependencies are elements in a parameter list.
