Another thing you can do is something like the following:

;GET ALL VALID OBJECTS
ov = obj_valid()

;COUNT THE INSTANCES OF YOUR CLASS
className = 'TheNameOfYourClass'
count = 0
for i=0,n_elements(ov)-1 do begin
if obj_isa(ov[i],className) gt 0 then count++
endfor;i
print,count

;IF YOU WANT THE OBJECT REFERENCE(S)
if count gt 0 then begin
ref = obj_arr(count)
for i=0,n_elements(ov)-1 do begin
if obj_isa(ov[i],className) gt 0 then ref = ov[i]
endfor;i
endif

This would retrieve all subclasses of the class you are
interested in, so you might want to do something more to
search for the specific class you need.

You probably wouldn't want to do this in a program, but
it could be useful at times.
