Interface ICriteria

public interface ICriteria

Criteria helps for retrieving results from the provider search by composing Criterion objects. The IUserSearchManager is a factory for Criteria. Criterion instances are obtained via ISelection methods. Criteria can deal with different kind of criterion, as logical or just simple expression. The typical usage of the Criteria is as follows:

      ISelection selection = ...
                ICriterion name = selection.eq("name", "value");
                ICriterion host = selection.eq("host", "value");
                ICriterion and = selection.and(name, host);
                ICriteria criteria = ...
                criteria.add(and);
