virtualost::CommandOptionParse::~CommandOptionParse()[purevirtual]
       Virtual destructor needed so that the object may be correctly deleted.

       This is the CommandOptionParse interface class.

       To implement this object you can call makeCommandOptionParse(); This will instantiate a dynamically
       allocated version of this class and parse the command line for the list of command options that are
       passed in.

virtualboolost::CommandOptionParse::argsHaveError()[purevirtual]
       Get the value of the error flag set if the parser encountered errors.

       Examplescmdlineopt.cpp.

   virtualvoidost::CommandOptionParse::performTask()[purevirtual]
       The method should be invoked by the main code once it has determined that the application should be
       started.

       Examplescmdlineopt.cpp.

   virtualconstchar*ost::CommandOptionParse::printErrors()[purevirtual]
       Return a string of text describing the list of errors encountered.

       Examplescmdlineopt.cpp.

   virtualconstchar*ost::CommandOptionParse::printUsage()[purevirtual]
       Return a string that contains the usage description of this list of paramaters.

       Examplescmdlineopt.cpp.

   virtualvoidost::CommandOptionParse::registerError(constchar*errMsg)[purevirtual]
       Register an error with this parser. This string will be appended to the errors already buffered in this
       object.
