CompositeUnaryPredicate (Commons Functor 1.0-SNAPSHOT API)

java.lang.Object
- org.apache.commons.functor.core.composite.CompositeUnaryPredicate<A>

Type Parameters:
A - the predicate argument type.

All Implemented Interfaces:

Serializable, Functor, UnaryFunctor<A>, UnaryPredicate<A>
```
public final class CompositeUnaryPredicate<A>
extends Object
implements UnaryPredicate<A>, Serializable
```
A UnaryPredicate representing the composition of UnaryFunctions, "chaining" the output of one to the input of another. For example,
```
new CompositeUnaryPredicate(p).of(f)
```
tests to p.test(f.evaluate(obj)), and
```
new CompositeUnaryPredicate(p).of(f).of(g)
```
tests to p.test(f.evaluate(g.evaluate(obj))).
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.
