Either (InterMine 5.0.0 API)

java.lang.Object
- org.intermine.webservice.server.core.Either<A,B>

Type Parameters:

A - The type of Lefts.

B - The type of Rights.

Direct Known Subclasses:

Either.Left, Either.Right
```
public abstract class Either<A,B>
extends java.lang.Object
```
Disjoint type union

Disjoint type union to handle certain features of the way we present results in outer-joined tables, but abstracted to be made more generally useful, and incorportating the visitor pattern for value access.

Obviously the terminology is taken from the worlds of functional programming (Haskell, Scala, et al.).
