# VERY nice function from Robert Klemme to check memory leaks
|
|
# and check on what GC has collected since last call.
|
|
#
|
|
# Usage can be:
|
|
#
|
|
# require 'swig_gc'
|
|
#
|
|
# GC.stats
|
|
# # do some stuff..
|
|
# GC.start # collect and report stats
|
|
# # do some more...
|
|
# GC.stats # just report stats
|
|
#
|
|
# or:
|
|
#
|
|
# require 'swig_gc'
|
|
#
|
|
# GC.track_class = String # track just String classes
|
|
# GC.stats
|
|
# # do some stuff..
|
|
# GC.start # collect and report stats
|
|
# # do some more...
|
|
# GC.stats # just report stats
|
|
