In a project of mine I'm using this annotation:
@Retention(RetentionPolicy.SOURCE)
@Target({ElementType.CONSTRUCTOR, ElementType.METHOD})
@Inherited
@Documented
public @interface ThreadConfined
{
ThreadType type();
}
public enum ThreadType
{
ANY, UI, NOT_UI
}
They are used to declare whether a method can be executed in any thread,
only in an UI thread (technology dependent), or must *not* be invoked in
a UI thread if the technology mandates that the UI thread must not be
blocked. Currently they are using for documentation purposes, but sooner
or later I'll write some Lombok extension for automatically generating
assertions.
AFAIK the Java-Concurrency annotations don't cover these semantics.
I'm near to move these annotations to my general stuff library, but
before doing I'm checking for existing stuff that does the same thing. I
don't seem to have found much, though:
+
http://plugins.netbeans.org/plugin/13880/checkthread-thread-safety-analysis-using-java-annotations
This is similar, but the forum is filled with porn spam, which seems to
indicate that the project is not alive aelend kicking.
+ http://www.checkthread.org/annotation-threadconfined.html

This is better, but it has some slightly different semantics (it
specifies enum values for the Swing EDT and SWT UI threads, while I
prefer to keep a generic UI). It could be worked around, though. I'm not
sure about the @Inherited thing, which is of primary importance to me (I
typically put annotations in MVC interfaces, which means that thread
confinement policies are "inherited" to implementation classes).
The major annoyance is that both projects aren't available in Maven
Repos, AFAIK. I already use a handful of projects that aren't in an
official Maven Repo, so I put them in my private repo, but I'm
struggling to solve this issue rather than add another.
Do you know something else that I should look at.
Suggestions?
Thanks.
PS This should be also a question for the Lombok mailing list, since
perhaps somebody is doing something similar, but given that Reiner is
reading here I'm not cross-posting...
