/**
 * A DDL constraint.
 * 
 * Constraint definitions can be used in DDL statements in order to specify the
 * constraint, or in some DML statements that reference a given constraint.
 * 

 * Example:
 * 

 * 

 * // Assuming import static org.jooq.impl.DSL.*;
 *
 * using(configuration)
 *    .alterTable(ACTOR)
 *    .add(constraint("actor_unique_name")
 *        .unique(ACTOR.FIRST_NAME, ACTOR.LAST_NAME))
 *    .execute();
 * 
 * 
 * Instances can be created using {@link DSL#constraint(Name)} and overloads.
