BAutolock

Derived from: none

Declared in: be/support/Autolock.h

Library: libbe.so

Summary

The BAutolock class provides an easy mechanism for automatically locking and unlocking a BLocker object or, more typically, a BLooper. All you need to do is allocate a BAutolock object on the stack and pass it a target BLocker or BLooper. You may want to make sure the lock is in place before proceeding:

   BAutolock autolocker(myWindow);
   if ( autolocker.IsLocked() ) {
       . . .
   }

When the stack frame is destroyed, the BAutolock object unlocks the target object and then is itself destroyed.
