parseValue()

bool IntegerCmdLineOptionParser::parseValue ( std::string  arguments, std::string  prefix  )

virtual

Parses the integer option value.

Parameters

arguments	The arguments of option.
prefix	The prefix of option.

Returns

True when parsing is ready.

Exceptions

IllegalCommandLine

If the arguments of option are erronous.
