The pattern matching is done by objects returned by the build_pattern method. The arguments passed in when a match is performed will vary depending on what class build_pattern returns. patternscg|_g|_|jdD]g}|jdrd}|dd}nd}|j |}|r|jj |M|jj |iy)N,!TrF) _pos_patterns _neg_patternssplit startswith build_patternappend)rr?r negatematchers rrz_PatternList.__init___s~~c*G!!#&!!"+((1G""))'2""))'2+rr rct)z)Abstract method to build a pattern object)NotImplementedErrorrs rrGz_PatternList.build_patternqs "!rctfd|jD}tfd|jD}|xr| S)z?Match a set of values against positive & negative pattern listsc3<K|]}|jywr7r-rpargss rrz'_PatternList.matches..yE2DQ  4(2Dc3<K|]}|jywr7rOrPs rrz'_PatternList.matches..zrSrT)anyrCrD)rrR pos_match neg_matchs ` rr-z_PatternList.matchesvs>E$2D2DEE E$2D2DEE *]*rN) r#r$r%r&r'r _AnyPatternrGr(r-rrrr>r>Ps2 33$"S"[" ++rr>c eZdZdZdedefdZy)WildcardPatternListz%Match names against wildcard patternsr rct|S)zBuild a wild card pattern)r rs rrGz!WildcardPatternList.build_patternsw''rN)r#r$r%r&r'r rGrrrr[r[s/(S(_(rr[c eZdZdZdedefdZy)HostPatternListz?Match host names & addresses against wildcard and CIDR patternsr rcN t|S#t$rt|cYSwxYw)z.Build a CIDR address or wild card host pattern)r ValueErrorrrs rrGzHostPatternList.build_patterns, 0"7+ + 0&w/ / 0s $$N)r#r$r%r&r' _HostPatternrGrrrr^r^sI0S0\0rr^N)r&rtypingrmiscrrrarYr r rr r>r[r^rrrrds*4'=> %|34  - - '*'7.7 0 0,+,+^(,( 0l 0r
