Syntax

(token, nextIndex) = Strings.scanToken(string, startIndex, unsigned=false);

Description

Function scanToken scans the string starting at index "startIndex" and returns the next token, as well as the index directly after the token. The returned token is a record that holds the type of the token and the value of the token:

Variable token.tokenType is an enumeration (emulated as a package with constants) that can have the following values:

import T = Modelica.Utilities.Types.TokenType;

Modelica line comments ("// ... end-of-line/end-of-string") as well as white space is ignored. If "unsigned=true", a Real or Integer literal is not allowed to start with a "+" or "-" sign.

Example

import Modelica.Utilities.Strings;
import T = Modelica.Utilities.Types.TokenType;
(token, index) := Strings.scanToken(string);
if token.tokenType == T.RealToken then
   realValue := token.real;
elseif token.tokenType == T.IntegerToken then
   integerValue := token.integer;
elseif token.tokenType == T.BooleanToken then
   booleanValue := token.boolean;
elseif token.tokenType == T.Identifier then
   name := token.string;
else
   Strings.syntaxError(string,index,"Expected Real, Integer, Boolean or identifier token");
end if;
