How do I get the instantiated name of a class

I don't understand what you refer with "the name of the item which created it", can you provide an example of what you expect as result?

$CLASSNAME($THIS) returns the actual class name of $this instance, not a superclass or the class where is executed (possibly a superclass).

Are you trying to get all of the classes that a class extends? You can do that like this:

	set classname = $CLASSNAME($THIS)
	&sql(select primarysuper into :super from %dictionary.compiledclass where id=:classname)
	w super,!
ObjectScript
ObjectScript

If you do that, super is a ~ separated list of the class and everything that it inherits from, which is probably actually more information than you need.

If you are looking for the class name where a currently-running method originates, you could also try:

	set method = $CLASSNAME($THIS)_"||"_$P($Stack($stack,"PLACE"),"+",1)
	&sql(select Origin into :origin from %Dictionary.CompiledMethod where ID1 = :method)
	w origin,!
ObjectScript
ObjectScript

Use %Classname(1) method?

Hi,

so just to summarize what i understood. 

You have a superclass with some logging method. Now every time the logging method is called from a child class it logs the name of the superclass instead of the Child class?

If so the issue is that $CLASSNAME returns the name of the class where the method is located not where a method is called from.

To work around this behaviour you would need to rewrite your logging method to be a codegenerator, e.g.

instead of:

ClassMethod Log()
{
    w $CLASSNAME()
}
ObjectScript
ObjectScript

rewrite it like this:
 

ClassMethod Log() [ codemode = generator, forcegenerate ]
{
    do %code.WriteLine("    w $CLASSNAME()")
    quit 1
}
ObjectScript
ObjectScript

This will locate the Log method from the superclass to the child class and have $CLASSNAME resolve to the child classname.
