cmdOptionExists()

bool InputParser::cmdOptionExists ( const std::string & option ) const

inlinenodiscard

Checks whether provided command line option exists.

Parameters

[in]

option

Option to check

Returns

true If the provided option is found

false If the provided option is not found

getCmdOption()

const std::string & InputParser::getCmdOption ( const std::string & option ) const

inlinenodiscard

Gets single command line input

Parameters

[in]

option

Option to check

Returns

const std::string& Found command line input. Empty string if not found
