Interface CompoundPredicate

All Superinterfaces:

Predicate

public interface CompoundPredicate

extends Predicate

A CompundPredicate is a set of predicates connected by logical or relational operators. For example, age < 30 AND salary > 50K is a compound predicate which is connected by a boolean and operator.

Another example on surrogates is a set of simple predicates age < 30, income > 50K, and education = college, with each predicate connected with surrogate operator. If the first predicate cannot be evaluated because the age attribute has a missing value, the next predicate is to be evaluated, in the order of the predicates returned from getPredicates method.
