trait LazyParameterInterpreterFunction extends AnyRef
LazyParameterInterpreter is used to evaluate LazyParamater[T]. It has to be tied to operator's lifecycle to avoid leaking of resources. Because of this if you need to evaluate parameter, you always need to mixin this trait. Please note that exception thrown during LazyParameter evaluation should be handled - e.g. be wrapping in handling/collect methods
