  • All Implemented Interfaces:
    Serializable, Parameter

    A pico container "parameter" which allows one to make setter injection optional.

    This class is a hack of pico container... it should be used with care.

      • isResolvable

        public boolean isResolvable​(PicoContainer container,
                                    ComponentAdapter adapter,
                                    Class expectedType)
        Always return true, because since the setter is optional even its not in the container we can always resolve to null.
