The QReadLocker class is a convenience class that simplifies locking and unlocking read-write locks for read access.
The purpose of QReadLocker (and QWriteLocker) is to simplify QReadWriteLock locking and unlocking. Locking and unlocking statements or in exception handling code is error-prone and difficult to debug. QReadLocker can be used in such situations to ensure that the state of the lock is always well-defined.
Here's an example that uses QReadLocker to lock and unlock a read-write lock for reading:
QReadWriteLock lock;
QByteArray readData()
{
QReadLocker locker(&lock);
...
return data;
}
It is equivalent to the following code:
QReadWriteLock lock;
QByteArray readData()
{
lock.lockForRead();
...
lock.unlock();
return data;
}
The QMutexLocker documentation shows examples where the use of a locker object greatly simplifies programming.

protected |
| QtCore.QReadLocker.QReadLocker | ( | QReadWriteLock | readWriteLock | ) |
Constructs a QReadLocker and locks lock for reading. The lock will be unlocked when the QReadLocker is destroyed. If lock is zero, QReadLocker does nothing.
