Someone else might find this bit of code useful:
It’s a simple idea but I find it helps somewhat: a class with a private field and methods that pass the field to a receiver method whilst holding a lock (or, alternatively, requiring that you be on the UI thread).
The effect is that it’s harder to forget to take a lock because the data you want to access won’t be in scope unless you go via the ThreadBox.
There are obviously two ways to break this guarantee:
- Nothing stops you from entering the box and then copying the protected reference somewhere else.
- If you switch thread contexts inside the scope of the box, you still have access to the original data but the lock may not be held.
