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

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

All Implemented Interfaces:

Serializable, Functor, UnaryFunction<A,T>, UnaryFunctor<A>
```
public final class UnaryProcedureUnaryFunction<A,T>
extends Object
implements UnaryFunction<A,T>, Serializable
```
Adapts a UnaryProcedure to the UnaryFunction interface by always returning null.
Note that although this class implements Serializable, a given instance will only be truly Serializable if the underlying procedure is. Attempts to serialize an instance whose delegate is not Serializable will result in an exception.
