未终止的非空案例块
该警告类别由 qmllint 拼写[unterminated-case] 。
未终结的非空案块
发生了什么？
switch 语句中的一个 case 块是非空的，但没有用 break、return 或 throw 语句终止。此外，也没有选择通过注释。
为什么会这样？
开关语句中的穿墙逻辑可能会引起混淆或被忽视。如果是有意为之，就应该用注释（如"// fallthrough"）明确标出。如果不是有意为之，警告则表示遗忘了终止语句。
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，可添加遗漏的终止语句或添加明确的选择注释，允许跳过逻辑：
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")
