java.lang.Object
- org.apache.commons.functor.adapter.ProcedureFunction<T>

Type Parameters:
T - the returned value type.

All Implemented Interfaces:

Serializable, Function<T>, Functor, NullaryFunctor
```
public final class ProcedureFunction<T>
extends Object
implements Function<T>, Serializable
```
Adapts a Procedure to the Function 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.
