Member Data Documentation

const MathParser\Lexing\TokenType::CloseParenthesis = 32

Token representing a closing parenthesis, i.e.

')'

const MathParser\Lexing\TokenType::Constant = 300

Token represented a known constant, e.g.

'pi'

const MathParser\Lexing\TokenType::FunctionName = 200

Token represented a function name, e.g.

'sin'

const MathParser\Lexing\TokenType::Identifier = 20

Token representing an identifier, i.e.

a variable name.

const MathParser\Lexing\TokenType::OpenParenthesis = 31

Token representing an opening parenthesis, i.e.

'('

const MathParser\Lexing\TokenType::Sentinel = 1000

Token representing a senitinel, for internal used in the Parser.
