question: public static void hiddenFromEncodedString ( ProjectFilterSettings result , String s ) { if ( s . length ( ) > 0 ) { int bar = s . indexOf ( FIELD_DELIMITER ) ; String categories ; if ( bar >= 0 ) { categories = s . substring ( 0 , bar ) ; } else { categories = s ; } StringTokenizer t = new StringTokenizer ( categories , LISTITEM_DELIMITER ) ; while ( t . hasMoreTokens ( ) ) { String category = t . nextToken ( ) ; result . removeCategory ( category ) ; } } }
target:  set the hidden bug categories on the specifed ProjectFilterSettings from an encoded string
