Re: [ajdt-dev] How to get the caller's details for a executionpointcut?

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Patil,
this is no AspectJ specific feature. You can call
Thread.getStrackTrace() to obtain the current stack trace inside java,
for example :

StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();

The array of StackTraceElement returned is the current stack trace (from
your main() or Thread.run() up to your current position). From there,
you can see who is calling you.
