Detailed Description

Parser for Unixesque command line args.

CommandLineParser is used to make the parsing of command line arguments easier. Command line arguments are broken down into two seperate categories.

Identifiers must start with a tag character(passed to constructor) to mark the string as an identifier
Arbitraryly long sequences of values can follow an identifier.

Identifiers are matched to ParseActions via addAction. A space delimited sequence of values in a std::istream& is passed to the ParseAction matching the identifier. The sequence of values passed to each ParseAction is determined by checking for the presense of the leading tag character. If it is there, it is assumed to be an identifier, if it is not, it is assumed to be a value.

Constructor & Destructor Documentation

Parse::CommandLineParser::CommandLineParser (  int    argc, char *    argv[], string    tagChars = "-" )

Parameters: argc  number of command line arguments argv  value of C-style command line arguments. argv[0] to argv[argc -1] must be valid. argv[0] is assumed to be the program name, and is thus ignored. tagChars  string that marks identifiers. All identifiers passed to the addAction() method must start with a character in tagChars, or else their matching ParseAction will not get called.
