- org.apache.commons.collections.functors.AllPredicate

All Implemented Interfaces:

Serializable, PredicateDecorator, Predicate
```
public final class AllPredicate
extends Object
implements Predicate, PredicateDecorator, Serializable
```
Predicate implementation that returns true if all the predicates return true. If the array of predicates is empty, then this predicate returns true.
NOTE: In versions prior to 3.2 an array size of zero or one threw an exception.

```
public AllPredicate(Predicate[] predicates)
```
    Constructor that performs no validation. Use getInstance if you want that.
    
    Parameters:
    predicates - the predicates to check, not cloned, not null
- Method Detail
  - getInstance
```
public static Predicate getInstance(Predicate[] 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:
    predicates - the predicates to check, cloned, not null
    
    Returns:
    the all predicate
    
    Throws:
    
    IllegalArgumentException - if the predicates array is null
    
    IllegalArgumentException - if any predicate in the array is null
  - getInstance
```
public static Predicate getInstance(Collection 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:
    predicates - the predicates to check, cloned, not null
    
    Returns:
    the all predicate
    
    Throws:
    
    IllegalArgumentException - if the predicates array is null
    
    IllegalArgumentException - if any predicate in the array is null
  - evaluate
```
public boolean evaluate(Object object)
```
    Evaluates the predicate returning true if all predicates return true.
    
    Specified by:
    
    evaluate in interface Predicate
    
    Parameters:
    object - the input object
    
    Returns:
    true if all decorated predicates return true
  - getPredicates
```
public Predicate[] getPredicates()
```
    Gets the predicates, do not modify the array.
    
    Specified by:
    
    getPredicates in interface PredicateDecorator
    
    Returns:
    the predicates
