# A literal (value) is a token that represents a data value in the parsed
# language. For instance, in Ruby data values such as strings, numbers,
# regular expression,... can appear directly in the source code. These are
# examples of literal values. One responsibility of a tokenizer/lexer is
# to convert the text representation into a corresponding value in a
# convenient format for the interpreter/compiler.
class Literal < Token
# @return [Object] The value expressed in one of the target datatype.
attr_reader(:value)
# Constructor.
# @param aValue [Object] value of the token in internal representation
# @param theLexeme [String] the lexeme (= piece of text from input)
# @param aTerminal [Syntax::Terminal, String]
# @param aPosition [Rley::Lexical::Position] line, column position pf token
def initialize(aValue, theLexeme, aTerminal, aPosition = nil)
