Examples of org.openfaces.component.filter.FilterCriterion

org.openfaces.component.filter.FilterCriterion
An abstract base class for all filter criterion classes. A filter criterion is an entity that identifies a rule for passing or rejecting data objects during the filtering procedure. The actual rule is defined in the concrete implementations of this class. @author Dmitry Pikhulya
