Sawyer::CommandLine::ShowVersion Class Reference

ShowVersion()

Sawyer::CommandLine::ShowVersion::ShowVersion ( const std::string &  versionString )

Constructor for derived classes.

Non-subclass users should use instance instead.

Member Function Documentation

instance()

static Ptr Sawyer::CommandLine::ShowVersion::instance ( const std::string &  versionString )

static

Allocating constructor.

Returns a pointer to a new ShowVersion object. Uses will most likely want to use the showVersion factory instead, which requires less typing.
