未结束的非空 case 代码块
qmllint 将此警告类别拼写为“[unterminated-case] ”。
未结束的非空 case 代码块
发生了什么？
switch 语句中的某个 case 代码块内容不为空，但未通过 break、return 或 throw 语句结束。此外，该 code block 也没有包含“允许向下传递”的注释。
为什么这样不好？
switch 语句中的向下传递逻辑可能会令人困惑或被忽略。如果是故意设计的，应使用“// fallthrough”之类的注释明确标注。如果并非有意为之，则该警告表明遗漏了终止语句。
示例
switch (state) {
case Main.State.Reset:
clearState() // <--- "Unterminated non-empty case block"
case Main.State.Invalid:
asyncInitState()
return false
case Main.State.Initializing:
// wait for initialization to complete
return false
case Main.State.Ready:
res = lookup(query)
log(res.stats)
saveToDisk(res.data) // <--- "Unterminated non-empty case block"
default:
throw new InvalidStateException("Unknown state")
}要修复此警告，请添加缺失的终止语句，或添加明确允许落入后续逻辑的注释：
switch (state) {
case Main.State.Reset:
clearState()
// fallthrough // <--- add fallthrough comment
case Main.State.Invalid:
asyncInitState()
return false
case Main.State.Initializing:
// wait for initialization to complete
return false
case Main.State.Ready:
res = lookup(query)
log(res.stats)
saveToDisk(res.data)
return true // <--- add forgotten terminating statement
default:
throw new InvalidStateException("Unknown state")
