Re: [aspectj-dev] [NEWBIE] Return type for the method is missing
|
Welcome to AspectJ...
This is a question for aspectj-users@xxxxxxxxxxx,
where people discuss how to write AspectJ programs.
The compiler error message here is not helpful,
but here's the problem:
from: after : logEntry() {
to: after () : logEntry() {
When starting, I recommend keeping the two-page
quick reference and the language semantic appendix
at your side; once you've gotten the syntax, errors
like this jump out at you, and it becomes easy to
write code.

P.S. - There's a bug on point:

Using: AspectJ v1.1.1 (as reported by ajc -version)
OK, so I am just starting out with AOP and AspectJ.
I have a simple ol' Java class:
public class MainClass {
public void wasteTime(int duration) {
try {
Thread.sleep(duration*1000);
} catch (InterruptedException e) {
System.out.println("Sleep interrupted");
}
}
}
I then wrote an aspect with a a couple of pointcuts and a few advices. Upon compilation these generate all kinds of errors. I have whittled it down to one pointcut and one advice.
public aspect Timer {
pointcut logEntry() : call(* MainClass.wasteTime(..));
after : logEntry() {
System.out.println("foo");
}
}
This generates 3 errors:
Timer.java:18 Return type for the method is missing
pointcut logEntry() : call(* MainClass.wasteTime(..));
^^^^
Timer.java:21 Syntax error on token ":", "(" expected
after : logEntry() {
^
Timer.java:21 Return type for the method is missing
after : logEntry() {
^^^^^^^^^^
Can you help?
