# Small helper class. Instanciate with
|
|
# transform = CFMapTransformer(key)
|
|
# or
|
|
# transform = CFMapTransformer(key, map)
|
|
# default map value is to use The map of current event.
|
|
#
|
|
# The key is used to keep track of transform. Different transforms
|
|
# on same map should use different key to prevent mixup
|
|
|
|
# transformAll(criteria,whatTo)
|
|
# criteria can be a single String or a list,
|
|
# whatTo can be a single String or a list.
|
|
# This will scan the whole map for item's whose
|
|
# "name" are in the list of criteria and transform
|
|
# the to one of the whatTo objects, choosen randomly.
|
|
# original object is kept in inventory of newly created
|
|
# item and can be restored from there
|
|
# untransformAll()
|
|
# this no argument method cancel all changes that have been
|
|
# made by transformAll
