virtual bool argMatches(const std::string &s) const
A method that tests whether a string matches this argument.
bool _alreadySet
Indicates whether the argument has been set.
bool combinedSwitchesMatch(std::string &combined)
Checks a string to see if any of the chars in the string match the flag for this Switch.
A virtual base class that defines the essential data for all arguments.
Thrown from CmdLine when the arguments on the command line are not properly specified, e.g.
A simple switch argument.
virtual void reset()
Clears the Arg object and allows it to be reused by new command lines.
bool _xorSet
Indicates that the arg was set as part of an XOR and not on the command line.
static char delimiter()
The delimiter that separates an argument flag/name from the value.
bool getValue()
Returns bool, whether or not the switch has been set.
virtual bool processArg(int *i, std::vector< std::string > &args)
Handles the processing of the argument.
bool _value
The value of the switch.
bool _default
Used to support the reset() method so that ValueArg can be reset to their constructed value...
void _checkWithVisitor() const
Performs the special handling described by the Vistitor.
static const std::string nameStartString()
A base class that defines the interface for visitors.
The base class that manages the command line definition and passes along the parsing to the appropria...
virtual std::string toString() const
Returns a simple string representation of the argument.
virtual void add(Arg &a)=0
Adds an argument to the list of arguments to be parsed.
bool _ignoreable
Whether this argument can be ignored, if desired.
static bool ignoreRest()
Whether to ignore the rest.
virtual void reset()
Clears the Arg object and allows it to be reused by new command lines.
static char blankChar()
The char used as a place holder when SwitchArgs are combined.
SwitchArg(const std::string &flag, const std::string &name, const std::string &desc, bool def=false, Visitor *v=NULL)
SwitchArg constructor.
std::string _flag
The single char flag used to identify the argument.
