I'm not an ObjC expert, but I think the @synchronize directive works more or less like synchronized methods in Java do.


Many people have mentioned this, but when I ask them about how to use it, I just get blank stares. I found just ONE technote that mentioned

the object pointing to the class I'm in when I call it?


As I understand it, the object is essentially arbitrary. It is used as the key to look up (or create as necessary) a recursive mutex, which is presumably destroyed when the object is deallocated. As such, every object pointer identifies a mutex. As such, it's logical to choose an object representing the required degree of granularity - either the root object of a larger structure, or the specific object which is being modified.


Can you translate that into English, in such a way as to allow me to determine which Object I'm
supposed to pass to @synchronize? I still don't have an answer to that.


John
