Constructor Detail

AllPredicate

public AllPredicate(Predicate<? super T>[] predicates)
Constructor that performs no validation. Use getInstance if you want that.

Parameters:
predicates - the predicates to check, not cloned, not null

getInstance

public static <T> Predicate<T> getInstance(Collection<Predicate<? super T>> predicates)
Factory to create the predicate.

Parameters:
predicates - the predicates to check, cloned, not null

IllegalArgumentException - if the predicates array is null
IllegalArgumentException - if any predicate in the array is null
IllegalArgumentException - if the predicates array has less than 2 elements

evaluate

public boolean evaluate(T object)
Evaluates the predicate returning true if all predicates return true.

Specified by:
evaluate in interface Predicate<T>
Parameters:
object - the input object
