Examples of ket.math.purpose.VariableToken

ket.math.purpose.VariableToken
Represent a variable either as a Symbol, CompoundState or as a Word. This exists largely for the instanceof test that it enables.

          Token unknown = readNextSymbol(equation, knownArguments);
          tokenList.append(unknown);
          continue;
        }
        Word word = new Word(string);
        Token variable = new VariableToken(word);
        tokenList.append(variable); 
      } else { 
        Token unknown = readNextSymbol(equation, knownArguments);
        tokenList.append(unknown);
      }
