java.lang.Object
- org.apache.commons.functor.core.composite.ConditionalUnaryFunction<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 ConditionalUnaryFunction<A,T>
extends Object
implements UnaryFunction<A,T>, Serializable
```
A UnaryFunction similiar to Java's "ternary" or "conditional" operator (? :). Given a predicate p and functions f and g, evalautes to p.test(x) ? f.evaluate(x) : g.evaluate(x).
Note that although this class implements Serializable, a given instance will only be truly Serializable if all the underlying functors are. Attempts to serialize an instance whose delegates are not all Serializable will result in an exception.
