Dear all,
I want to implement something like these:
* x = AtomicPointer.@get (ref atomicRef) // reader
* AtomicPointer.@set (ref atomicRef, newref) // writer
* return AtomicPointer.@get (ref atomicRef) // reader
but have the benefit of vala ref counting.
The best I can think of is:
* lock (atomicRef) { x = atomicRef; }
* lock (atomicRef) { atomicRef = newref; }
* lock (atomicRef) { return atomicRef; }
But lock is too course.
e.g., lock (atomicRef) {x = atomicRef;} will also lock
out other readers, whereas AtomicPointer.get won't.
I realise that the exclusive region is small.
But if you have a lot of readers, the effect
may be significant.
Any suggestions?
Nice day
