predicates

evaluate
public boolean evaluate(Object object)
Evaluates the predicate returning true if all predicates return true.
- evaluate in interface Predicate
object
- the input object
- true if all decorated predicates return true
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.
