Token

java.lang.Object
- com.dashoptimization.objects.Token

All Implemented Interfaces:

java.lang.Comparable<Token>
```
public final class Token
extends java.lang.Object
implements java.lang.Comparable<Token>
```
A token in a non-linear formula. All constructors of this class are private. Use the various static factory functions to get new instances. This avoids creating multiple instances that refer to the same token (like for example the EOF token.
