the variable '_class_prefixes' of stringify.StringifyMixin is used to help the
method 'from_jsondict()' to create the class instance.
'_class_prefixes' requires a list of the class names.
some classes have another list of the class names alreadly.
this patch adds a method which makes '_class_prefixes' by using the existing
list.
before applying this patch:
(e.g. ryu.lib.packet.ipv6)
# append the name to another list
@ipv6.register_header_type(inet.IPPROTO_HOPOPTS)
class hop_opts(opt_header):
...
@ipv6.register_header_type(inet.IPPROTO_DSTOPTS)
class dst_opts(opt_header):
....
# append the name again
ipv6._class_prefixes = ['hop_opts', 'dst_opts', ...]
after applying this patch:
(e.g. ryu.lib.packet.ipv6)
# append the name to another list
@ipv6.register_header_type(inet.IPPROTO_HOPOPTS)
class hop_opts(opt_header):
...
@ipv6.register_header_type(inet.IPPROTO_DSTOPTS)
class dst_opts(opt_header):
....
# create the new list from another list
ipv6.set_classes(ipv6._IPV6_EXT_HEADER_TYPE)
