        EqualZero

All Implemented Interfaces:

Serializable, Cloneable

Enclosing class:

EltRangeInt
```
public static class EltRangeInt.EqualZero
extends EltRangeInt
```
Internal invariant representing long scalars that are equal to zero. Used for non-instantiating suppressions. Will never print since OneOf accomplishes the same thing.
