Detailed Description

A simple switch argument.

If the switch is set on the command line, then the getValue method will return the opposite of the default value for the switch.This version of SwitchArg patches an invalid array access. See cmdLine/cmdSwitchArg.h in VR-Link for the original.

Constructor & Destructor Documentation

makVrv::SwitchArg::SwitchArg ( const std::string &  flag, const std::string &  name, const std::string &  desc, bool  def, DtCmdLine::Visitor *  v = NULL  )

inline

SwitchArg constructor.

Parameters

flag	- The one character flag that identifies this argument on the command line.
name	- A one word name for the argument. Can be used as a long flag on the command line.
desc	- A description of what the argument is for or does.
def	- The default value for this Switch.
v	- An optional visitor. You probably should not use this unless you have a very good reason.

makVrv::SwitchArg::SwitchArg ( const std::string &  flag, const std::string &  name, const std::string &  desc, bool  def, DtCmdLine::CmdLineInterface &  parser, DtCmdLine::Visitor *  v = NULL  )

inline

SwitchArg constructor.

Parameters

flag	- The one character flag that identifies this argument on the command line.
name	- A one word name for the argument. Can be used as a long flag on the command line.
desc	- A description of what the argument is for or does.
parser	- A CmdLine parser object to add this Arg to
def	- The default value for this Switch.
v	- An optional visitor. You probably should not use this unless you have a very good reason.

Member Function Documentation

bool makVrv::SwitchArg::processArg ( int *  i, std::vector< std::string > &  args  )

inlinevirtual

Handles the processing of the argument.

This re-implements the Arg version of this method to set the _value of the argument appropriately.

Parameters

i	- Pointer the the current argument in the list.
args	- Mutable list of strings. Passed in from main().

References _value, and combinedSwitchesMatch().

bool makVrv::SwitchArg::combinedSwitchesMatch ( std::string &  combined )

inline

Checks a string to see if any of the chars in the string match the flag for this Switch.

Referenced by processArg().

bool makVrv::SwitchArg::getValue ( ) const

inline

Returns bool, whether or not the switch has been set.

References _value.

makVrv::SwitchArg::operator bool ( )
