Class CriteriaTool<UJO extends Ujo>

java.lang.Object
  org.ujoframework.criterion.CriteriaTool<UJO>

public class CriteriaTool<UJO extends Ujo>
extends java.lang.Object

The Criteria class is a simple tool to search UJO objects in the list. This class takes full advantage of architecture UJO objects. See the next sample.

 Person child  = new Person("Pavel", 140.0);
 Person mother = new Person("Mary", 150.0);
 Person father = new Person("John", 160.0);

 child.set(MOTHER, mother);
 child.set(FATHER, father);

 List<Person> persons = Arrays.asList(child, mother, father);

 Criterion<Person> exp = Criterion.where(NAME, "John");
 UjoComparator<Person> sort = UjoComparator.create(HIGH, NAME);
 List<Person> result = CriteriaTool.where().select(persons, exp, sort);
