- org.apache.commons.functor.core.composite.TransposedPredicate<L,R>

Type Parameters:
L - the left argument type.
R - the right argument type.

All Implemented Interfaces:

```
public class TransposedPredicate<L,R>
extends Object
implements BinaryPredicate<L,R>
```
Transposes (swaps) the arguments to some other predicate. For example, given a predicate p and the ordered pair of arguments a, b. tests p.test(b,a).
