현재 문서의 사용자가 코드 섹션을 동시에 실행하지 못하도록 하는 잠금을 가져옵니다. 문서 잠금으로 보호되는 코드 섹션은 서로 다른 문서의 컨텍스트에서 실행되는 스크립트 인스턴스에서 동시에 실행할 수 있지만, 특정 문서에 대해 한 번만 실행할 수 있습니다. Lock.tryLock(timeoutInMillis) 또는 Lock.waitLock(timeoutInMillis)가 호출될 때까지는 실제로 잠금이 획득되지 않습니다. 이 메서드가 포함된 문서의 컨텍스트 외부에서 호출되면 (예: 독립형 스크립트 또는 웹앱에서) null이 반환됩니다.

A code section guarded by a document lock can be executed simultaneously by script\ninstances running in the context of different documents, but by no more than one execution for\nany given document. Note that the lock is not actually acquired until [Lock.tryLock(timeoutInMillis)](/apps-script/reference/lock/lock#tryLock(Integer))\nor [Lock.waitLock(timeoutInMillis)](/apps-script/reference/lock/lock#waitLock(Integer)) is called.
