Whitespace-а ще ти коства поне 1 точка, ако го запазиш както е в момента. Отделно е добре JumpInterface и JumpInterfaceHelper да бъдат преместени в Asm. Няма ли да имплементираш всички jump-ове, също така?
В кода има голямо количество повторения, което ще затрудни евентуален refactoring, или промяна/добавяне на функционалност. Погледни DRY принципа и виж какво можеш да направиш по въпроса.
Нямаше кога да го направя, за съжаление съм доста зает напоследък. Иначе не виждам Whitespace ,нито на скептик нито на око.а за JumpInterface и JumpInterfaceHelper немогат да са в асм заради най-много 9те метода на клас. П.с Благодаря за фийдбека :)
