I guess you can
I never tried but it occurs to me that you could do something like:
** Error event inside your class
PROCEDURE ERROR
LPARAMETERS nError, cMethod, nLine
** you could monitor the error number and determine what action to
take, with a do case construct
do case
case nError = ........
do something
case nError = ........
do something else
otherwise
this.destroy()
endcase
ENDPROC
Again, I emphasize, I never tried this

release object
is what I do all the time. The situation here is that the error
occurs inside the object. Can you release an object in its error method?

Check Help on RELEASING OBJECTS and related
I usually do something like this:
do form myform name oForm linked
do things with the oForm object properties and then
oForm.release
oForm = NULL
Of course that applies to a form, thus the call to the release
method. For another object do something like:
oObj = createobject('xxx')
release oObj
oObj = NULL
If the class is derived from a procedure in a prg
set procedure to myproc.prg additive && contains the class 'myclass'
oObj = createobject('myclass')
Use the object and then kill it:
release oObj
oObj = NULL
and finally, you can kill the procedure with
Release procedure myproc.prg

I guess I did not make myself clear. I have an import object. It
has no interface and is based on a custom class. It opens tables,
does queries on sql server tables and then populates the tables and
runs as a server so to speak. It does the import every 10 minutes.
I have been using this class for over 10 years and I am modifying a
few things. In my modifications I have done something wrong and I
get an error. I want to stop the process completely at that point,
but can't figure out how to do it. Does destroy() do that? I am
running it in a top level form. Maybe clear events will work?

What is the proper way to "release" a class?
------------------------
Something sounds wrong. How do you know you should exit? Returning
0 rows
or you get a 0 back when it should return the ID #?
