public TransformedPredicate(Transformer<? super T,? extends T> transformer,
                    Predicate<? super T> predicate)
```
    Constructor that performs no validation. Use transformedPredicate if you want that.
    
    Parameters:
    transformer - the transformer to use
    predicate - the predicate to decorate

  - transformedPredicate
```
public static <T> Predicate<T> transformedPredicate(Transformer<? super T,? extends T> transformer,
                                    Predicate<? super T> predicate)
```
    Factory to create the predicate.
    
    Type Parameters:
    T - the type that the predicate queries
    Parameters:
    transformer - the transformer to call
    predicate - the predicate to call with the result of the transform
    
    Returns:
    the predicate
    
    Throws:
    
    IllegalArgumentException - if the transformer or the predicate is null
  - evaluate
```
public boolean evaluate(T object)
```
    Evaluates the predicate returning the result of the decorated predicate once the input has been transformed
    
    Specified by:
    
    evaluate in interface Predicate<T>
    
    Parameters:
    object - the input object which will be transformed
    
    Returns:
    true if decorated predicate returns true
  - getPredicates
```
public Predicate<? super T>[] getPredicates()
```
    Gets the predicate being decorated.
    
    Specified by:
    
    getPredicates in interface PredicateDecorator<T>
    
    Returns:
    the predicate as the only element in an array
