Detailed Description

Manages the command line parsing object.

The base class that manages the command line definition and passes along the parsing to the appropriate Arg classes.

Definition at line 49 of file cmd_line.hpp.


Constructor & Destructor Documentation

ecl::CmdLine::CmdLine ( const std::string &  message,
const char  delimiter = ' ',
const std::string &  version = "none",
bool  helpAndVersion = true 
) [inline]

Command line constructor. Defines how the arguments will be parsed.

Parameters:
message- The message to be used in the usage output.
delimiter- The character that is used to separate the argument flag/name from the value. Defaults to ' ' (space).
version- The version number to be used in the --version switch.
helpAndVersion- Whether or not to create the Help and Version switches. Defaults to true.

Definition at line 257 of file cmd_line.hpp.

Member Data Documentation

std::list<Arg*> ecl::CmdLine::_argDeleteOnExitList [protected]
