Re: [CFCDev] Programmatically determining a method call

[Matt Liotta]

Ok now I understand what you have done... I tought that I will know 
who has
called the method... because right now, on all my methods I have the 
first
arguments wich is .. <cfargument name="in_callername ... ">.... on 
every
method I have this first argument.... just to know who has called the
method... for debugging purposes... If I could use your code to know 
whose
calling... I will not need this argument on every method...

Using the same technique I have created the following example CFC that 
now returns an array of methods. The array will contain all methods in 
the stack that were used to call the final method with my code in it. 
Further, the array is ordered equivalent to the order in which the 
methods appeared on the stack i.e. array[1] is the last method called.

<cfcomponent>
	<cffunction name="getCaller" returntype="array" access="public">
		<cfscript>
			e = CreateObject("java", "java.lang.Exception");
			sts = e.getStackTrace();
			methodStack = "";
			for(itr = 1; itr lte ArrayLen(sts); itr = itr + 1) {
				className = sts[itr].getClassName();
				if(className contains "2ecfc") {
					methodName = sts[itr].getClassName();
					index = Find("$func", methodName);
					if(Len(methodStack) eq 0)
						methodStack = Mid(methodName, index + 5, Len(methodName));
					else
						methodStack = methodStack & "," & Mid(methodName, index + 5, 
Len(methodName));
				}
			}
		</cfscript>
		<cfreturn ListToArray(methodStack)>
	</cffunction>
	<cffunction name="foo" returntype="array" access="public">
		<cfreturn getCaller()>
	</cffunction>
	<cffunction name="bar" returntype="array" access="public">
		<cfreturn foo()>
	</cffunction>
</cfcomponent>
