lock(whenCondition:before:)
Attempts to acquire a lock before a specified moment in time.
Declaration
func lock(whenCondition condition: Int, before limit: Date) -> BoolParameters
- condition:
The condition to match on.
- limit:
The date by which the lock must be acquired or the attempt will time out.
Return Value
true if the lock is acquired within the time limit, false otherwise.
Discussion
The receiver’s condition must be equal to condition before the locking operation will succeed. This method blocks the thread’s execution until the lock can be acquired or limit is reached.
