IsLessThan (Apache Commons Functor 1.0-SNAPSHOT API)

java.lang.Object
- org.apache.commons.functor.core.comparator.IsLessThan<T>

Type Parameters:
T - the binary predicate input types

All Implemented Interfaces:

BinaryFunctor<T,T>, BinaryPredicate<T,T>, Functor
```
public final class IsLessThan<T>
extends Object
implements BinaryPredicate<T,T>
```
A BinaryPredicate that tests true iff the left argument is greater than the right argument under the specified Comparator. When no (or a null Comparator is specified, a Comparable Comparator is used.
