I'd like to somehow find out which CFC is calling my method.
I have a logging CFC which is called by many different CFC's. On this logging CFC there's a need to store which CFC called for the log.
Whilst I could simply pass the CFC name as an argument to my log.cfc, I find this to be a repetitive task, that might not be necessary, if I somehow could find out "who's" calling the method on log.cfc
Is there any programmatic way of achieving this?
Thanks in advance
Update: As Richard Tingle's answer points out, since CF10 you can use CallStackGet(), which is better than throwing a dummy exception.
Original answer: The easiest way is to throw a dummy exception and immediately catch it. But this has the downside of making a dummy exception show up in your debug output. For me, this was a deal-breaker, so I wrote the following code (based off of this code on cflib). I wanted to create an object that is similar to a cfcatch object, so that I could use it in places that expected a cfcatch object.
Note: You may have to adjust this code a bit to make it work in CF8 or earlier. I don't think the {...}
syntax for creating object was supported prior to CF9.
StackTrace = {
Type= 'StackTrace',
Detail= '',
Message= 'This is not a real exception. It is only used to generate debugging information.',
TagContext= ArrayNew(1)
};
j = CreateObject("java","java.lang.Thread").currentThread().getStackTrace();
for (i=1; i LTE ArrayLen(j); i++)
{
if(REFindNoCase("\.cf[cm]$", j[i].getFileName())) {
ArrayAppend(StackTrace.TagContext, {
Line= j[i].getLineNumber(),
Column= 0,
Template= j[i].getFileName()
});
}
}
