Token

java.lang.Object
- processing.app.syntax.Token

```
public class Token
extends java.lang.Object
```
A linked list of tokens. Each token has three fields - a token identifier, which is a byte value that can be looked up in the array returned by SyntaxDocument.getColors() to get a color value, a length value which is the length of the token in the text, and a pointer to the next token in the list.
