Static Imports
org.apache.commons.collections4.functors.FunctorUtils.coerce, .FunctorUtils.validate, .TruePredicate.truePredicate
Predicate implementation that returns true if all the predicates return true. If the array of predicates is empty, then this predicate returns true.

AllPredicateback to summary
public AllPredicate(final Predicate<? super T>... predicates)

Constructor that performs no validation. Use allPredicate if you want that.

Parameters
predicates:Predicate<? super T>[]

the predicates to check, not cloned, not null

Method Detail

allPredicateback to summary
public static <T> Predicate<T> allPredicate(final Predicate<? super T>... predicates)

Factory to create the predicate.

If the array is size zero, the predicate always returns true. If the array is size one, then that predicate is returned.

Parameters
<T>
the type that the predicate queries
predicates:Predicate<? super T>[]

the predicates to check, cloned, not null

Returns:Predicate<T>

the all predicate

Exceptions
NullPointerException:
  • if the predicates array is null
  • if any predicate in the array is null
allPredicateback to summary
public static <T> Predicate<T> allPredicate(final Collection<? extends Predicate<? super T>> predicates)

Factory to create the predicate.

If the collection is size zero, the predicate always returns true. If the collection is size one, then that predicate is returned.

Parameters
<T>
the type that the predicate queries
predicates:Collection<? extends Predicate<? super T>>

the predicates to check, cloned, not null

Returns:Predicate<T>

the all predicate

Exceptions
NullPointerException:
  • if the predicates array is null
  • if any predicate in the array is null
evaluateback to summary
public boolean evaluate(final T object)

Implements org.apache.commons.collections4.Predicate.evaluate.

Evaluates the predicate returning true if all predicates return true.

Parameters
object:T

the input object

Returns:boolean

true if all decorated predicates return true
