Overview

NSRecursiveLock defines a lock that may be acquired multiple times by the same thread without causing a deadlock, a situation where a thread is permanently blocked waiting for itself to relinquish a lock. While the locking thread has one or more locks, all other threads are prevented from accessing the code protected by the lock.

Instance Method Details

- (Boolean) lockBeforeDate(limit)

Attempts to acquire a lock before a given date. The thread is blocked until the receiver acquires the lock or limit is reached.

Parameters:

  • limit (NSDate)

    The time before which the lock should be acquired.

Returns:

  • (Boolean)

    YES if the lock is acquired before limit, otherwise NO.

- (String) name

Returns the name associated with the receiver.

Returns:

  • (String)

    The name of the receiver.

- (Object) setName(newName)

Assigns a name to the receiver You can use a name string to identify a lock within your code. Cocoa also uses this name as part of any error descriptions involving the receiver.

Parameters:

  • newName (String)

    The new name for the receiver. This method makes a copy of the specified string.

Returns:

- (Boolean) tryLock

Attempts to acquire a lock, and immediately returns a Boolean value that indicates whether the attempt was successful.

Returns:

  • (Boolean)

    YES if successful, otherwise NO.
