Detailed Description

Grammar recognize value that can appear in right side of '=' operator in job options file.

Grammar's EBNF value ::= vectorvalue | vector_type | property_link. vectorvalue ::= pairvalue | literalvalue | mapvalue. literalvalue ::= realunits_grammar | boolean_grammar | string_grammar. mapvalue ::= literalvalue ('=' | ':') value. pairvalue ::= '(' vectorvalue ',' vectorvalue ')'. vector_type ::= ('{' vectorvalue_list '}') | ('[' vectorvalue_list ']'). vectorvalue_list ::= (vector_value (',' vector_value)*)?. property_link = '@' identifier_grammar ('.' identifier_grammar)+.

Grammar has two attributes

• boost::tuple<std::string,std::vector<std::string> 0 element contains string representation of top value 1 element contains vector representation of value (if it's vector)
• boost::tuple<int> nested level of vector
