|
The QgsReadWriteLocker class is a convenience class that simplifies locking and unlocking QReadWriteLocks.
|
|
|
|
Locking and unlocking a QReadWriteLocks in complex functions and statements or in exception handling code
|
|
is error-prone and difficult to debug.
|
|
QgsReadWriteLocker can be used in such situations to ensure that the state of the lock is always well-defined.
|
|
|
|
QgsReadWriteLocker should be created within a function where a QReadWriteLock needs to be locked.
|
|
The lock may be locked when QgsReadWriteLocker is created or when changeMode is called.
|
|
You can unlock and relock the lock with :py:func:`~unlock` and :py:func:`~changeMode`.
|
|
If locked, the lock will be unlocked when the QgsReadWriteLocker is destroyed.

Create a new QgsReadWriteLocker for ``lock`` and initialize in ``mode``.

|
%Docstring
|
|
Change the mode of the lock to ``mode``.
|
|
The lock will be unlocked and relocked as required.

void unlock();
|

%Docstring
|

Unlocks the lock.
|

Equivalent to doing ``changeMode( QgsReadWriteLocker.Unlock );``
