multithreading - Event Dispatch Thread meets the Java Memory Model -

-

It was already I asked, where the answer was:

is related to many fields Accessed by thread, it should be unstable or final, or arrive with synchronized blocks only. Otherwise, the assigned values ​​can not be visible to other threads.

Also, anything that manipulates pixels on the screen should be run from it, though it is handled transparently when using color / paint again.

Therefore, in my opinion, we need to worry about the memory model because the screen running on the phantom is somewhat simpler in the form of animation.

My question is, it is correct to understand, and for example the sun tutorial example. (Wrong)

You know, I think that you can be a point here. The TumbleItem code uses worker.isDone () to see if the work is completed or not. However, I do not think that it causes a complete "synchronize".

My reading of the JDK 1.6 code is that uses swingworker. ISDIN () FutureTask which is a sync Uses a vaporous state with attribute for the object isDone () does not seem to include the execution path synchronize method or block it happens.

I am not a real expert on newer concurrent classes, but I think that coolant should call worker.get () so that proper synchronization is guaranteed.

EDIT: I am talking about the use of EDT img array which is populated by the worker, however, it also appears that the use of the initial parameter by the EDT Is an issue with, as noted by @The Fist.

Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
