我有以下方法,我隻想測試event.status屬性,隻有當狀态已經傳入:
def findEvent(String desc, String status = null, Collection events) {
return events.find {
it.description == desc && \\If status is not null: it.status == status
}
throw new Exception("Review Event Record Not Found: ${desc}")
}
我以為可以這樣做,但似乎不起作用:
def findEvent(String desc, String status = null, Collection events) {
return events.find {
it.description == desc && (status != null ?: {it.status == status})
}
throw new Exception("Review Event Record Not Found: ${desc}")
}
有什麼辦法可以做到嗎?或者我必須回到這樣的事情:
if (status != null) {
return events.find {
it.description == desc && it.status == status
}
} else if (status == null) {
return events.find {
it.description == desc
}
}
有沒有一些最佳做法?
