Hi,
I'm trying to log read and write accesses with aspectJ.
To do this, I want to capture the constructor calls, read and write calls
and close calls of, for example, RandomAccessFile objects.
The logged data shall be saved inside the aspect. For this reason, I want to
use pertarget to capture constructor invocations. The problem is, that the
used pointcut doesn't seem to work; neither an aspect instance is created,
nor the advice for the constructor is used; i get a "advice has not been
applied" message.
These are the pointcuts used to capture the constructor calls.
public pointcut randomAccessFileCreation() : call(RandomAccessFile.new(..));
public pointcut writerCreation() : (call(FileWriter.new(..)) ||
call(PrintWriter.new(File,..)) || call(PrintWriter.new(String,..)));
These pointcuts (and more, for example readerCreation() following the same
principle) are joined with the newAspect() pointcut:
public pointcut newAspect() : writerCreation() ||
randomAccessFileCreation();
The aspect is defined like this:
public privileged aspect loggingAspect pertarget(newAspect()){
The advice belonging to the newAspect() pointcut:
after() returning(Object obj) : newAspect(){
boundTo = obj;
System.err.println("new Object " + boundTo);
log.setTimeOpen(Calendar.getInstance().getTime());
}
}
In the constructor of the aspect, i print a log message, too.
None of the log messages is printed during the execution of the program.
What am i doing wrong here?
Thanks
Christoph
