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:
java.lang.IllegalArgumentException
- if the predicates array is nulljava.lang.IllegalArgumentException
- if any predicate in the array is null
-
getInstance
public static Predicate getInstance(java.util.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:
java.lang.IllegalArgumentException
- if the predicates array is nulljava.lang.IllegalArgumentException
- if any predicate in the array is null
-
evaluate
public boolean evaluate(java.lang.Object object)
Evaluates the predicate returning true if all predicates return true.
-
getPredicates
public Predicate[] getPredicates()
Gets the predicates, do not modify the array.- Specified by:

in interfacePredicateDecorator
- Returns:
- the predicates
