java.lang.Object
- org.apache.commons.functor.adapter.BinaryFunctionUnaryFunction<A,T>

Type Parameters:
A - the argument type.
T - the returned value type.

All Implemented Interfaces:

Functor, UnaryFunction<A,T>, UnaryFunctor<A>
```
public final class BinaryFunctionUnaryFunction<A,T>
extends Object
implements UnaryFunction<A,T>
```
Adapts a BinaryFunction as a UnaryFunction by sending the same argument to both sides of the BinaryFunction. It sounds nonsensical, but using Composite functions, can be made to do something useful.
