Member Function Documentation

error() [1/2]

virtual void step::parser::error ( const std::string & msg )

virtual

Report a syntax error.

Parameters

msg	a description of the syntax error.

error() [2/2]

void step::parser::error

operator()()

int step::parser::operator()

(

)

Parse. An alias for parse ().
