struct map_descriptor {
MEDIUM: sample: add the "map" converter Add a new converter with the following prototype : map(<map_file>[,<default_value>]) map_<match_type>(<map_file>[,<default_value>]) map_<match_type>_<output_type>(<map_file>[,<default_value>]) It searches the for input value from <map_file> using the <match_type> matching method, and return the associated value converted to the type <output_type>. If the input value cannot be found in the <map_file>, the converter returns the <default_value>. If the <default_value> is not set, the converter fails and acts as if no input value could be fetched. If the <match_type> is not set, it defaults to "str". Likewise, if the <output_type> is not set, it defaults to "str". For convenience, the "map" keyword is an alias for "map_str" and maps a string to another string. The following array contains contains the list of all the map* converters. +----+----------+---------+-------------+------------+ | `-_ out | | | | | input `-_ | str | int | ip | | / match `-_ | | | | +---------------+---------+-------------+------------+ | str / str | map_str | map_str_int | map_str_ip | | str / sub | map_sub | map_sub_int | map_sub_ip | | str / dir | map_dir | map_dir_int | map_dir_ip | | str / dom | map_dom | map_dom_int | map_dom_ip | | str / end | map_end | map_end_int | map_end_ip | | str / reg | map_reg | map_reg_int | map_reg_ip | | int / int | map_int | map_int_int | map_int_ip | | ip / ip | map_ip | map_ip_int | map_ip_ip | +---------------+---------+-------------+------------+ The names are intentionally chosen to reflect the same match methods as ACLs use.
