I am using a tracing aspect and it is printing the method arg values upon entry, but without arg names: trace enter: int com.AjlibTest.DummyObject.someMethod(int) , this: com.AjlibTest.DummyObject@18941f7, args: arg 0 = 5 using joinPoint.getArgs() - I can see in the debugger that the arg names are not in the joinpoint - is there a way an aspect can capture that info? 10911 Watchful Fox Drive Austin, TX 78748 512 280-1753 Home 512 634-5148 Office 512 659-5300 Cell _______________________________________________ aspectj-users mailing list aspectj-users@... https://dev.eclipse.org/mailman/listinfo/aspectj-users |

I not only compile with -g, I am running within the eclipse debugger and I still get "arg 0". Plus doesn't thisJoinPoint.getArgs() do the same thing? Seems to, sorry I didn't read the aspectj src to confirm, I am downloading that today. if (joinPoint.getArgs() != null && joinPoint.getArgs().length>0) { Object getargs[] = joinPoint.getArgs();
CodeSignature codeSignature = (CodeSignature) joinPoint.getSignature(); String[] argNames = codeSignature.getParameterNames(); logStr.append(", args using CodeSignature: "+arguments(argNames)); logStr.append(", args using getArgs: "+arguments(argNames)); } return logStr.toString(); } protected String arguments(Object[] arguments) { StringBuffer logStr = new StringBuffer(); for (int i = 0; i < arguments.length; i++) { logStr.append((i>0 ? ", ":"")+ "arg "+i+" = "+traceString(arguments[i])); } return logStr.toString(); } console output: INFO com.AjlibTest.DummyObject - trace enter: int com.AjlibTest.DummyObject.someMethod(int) , this: com.AjlibTest.DummyObject@152544e, args using CodeSignature: arg 0 = i, args using getArgs: arg 0 = i -3 [main] owen Ramnivas Laddad wrote: If you compile your code using ajc or javac with -g (for binary weaving purpose), you will get the original argument names. -Ramnivas

Lord have mercy, ever wish you could take back a posting? I corrected my code, same results, the two lines below should have read: logStr.append(", args using CodeSignature: "+arguments(argNames)); logStr.append(", args using getArgs: "+arguments(getargs)); output is same darnit all owen From: Owen Corpening <owencorpening@...> To: aspectj-users@...

Aiieee thanks! the old "can't see my own handwriting" trick! Now calls to DummyObject.someMethod: public class DummyObject { public int someMethod(int i, int my2ndarg) log like this: -7 [main] INFO com.AjlibTest.DummyObject - trace enter: int com.AjlibTest.DummyObject.someMethod(int, int) , this: com.AjlibTest.DummyObject@152544e, args: i = 5, my2ndarg = 9 with this adjustment to the logging aspect: Object
arguments[] = joinPoint.getArgs(); CodeSignature codeSignature = (CodeSignature) joinPoint.getSignature(); String[] argNames = codeSignature.getParameterNames(); logStr.append(", args: "+arguments(argNames, arguments)); } return logStr.toString(); }
protected String arguments(String[] argNames, Object[] arguments) { StringBuffer logStr = new StringBuffer(); for (int i = 0; i < arguments.length; i++) { logStr.append((i>0 ? ", ":"")+ argNames[i] + " = " + traceString(arguments[i])); } return logStr.toString(); } much thanks, owen From: Ramnivas Laddad <ramnivas@...> To: aspectj-users@...

Does your method is declared as someMethod(int i)? Is so, the output seems to correctly print "i". You are getting "arg 0" part because you are printing "arg "+i.
