Hi again - and sorry for my high NG volume! I seem to keep bumping
into all kinds of problem today...
We are writing some code, that should NOT use static variables since
that may make later multi-threading or "componentization" of the code
more difficult than necessary.
Ah - "a case for AspectJ!" I thought at first but now I am running
into the problem, that AJDT seems to declare warnings only for files
within the same project. Is that so? Since when? I am pretty sure,
that I have written aspects that have worked accross project
boundaries under older AJDT versions (i.e. 1.1.10 and earlier).
I boiled that down to the following tiny example: a classes and an
aspect:
class Test: - has a static and a non-static field and fiddles a bit
with both...
---------------------------
package test;
public class Test
{
public static int a = 2;
public int b;
public Test() {
super();
methodA(a);
}
public void methodA(int x) {
System.out.println("methodA: " + x);
b = x;
a = x*2;
}
}
---------------------------
aspect FlagStatics: should flag accesses to the static field:
---------------------------
package test;
public aspect FlagStatics
{
pointcut allStaticVariableAccesses():
(
get(* test.*.*)
||
set(* test.*.*)
);
declare warning:
allStaticVariableAccesses()
: "Warning: use of static variable";
}
---------------------------
If the above two files reside within the same project things work and
the locations where the static field is set or used are properly
flagged.
If I separate these file into TWO projects, i.e. the file Test.java in
one project, the file FlagStatics.aj in another then no warnings are
emitted, no matter whether I make the first project import the second
or vice versa.
I tried the Java Build Path-s as well as the project references
settings, but couldn't get things to work. How do I apply an aspect
within a project to (an) other project(s)?
Michael
