AcmFilterCriterionSupplier

public AcmFilterCriterionSupplier(String key,
                                  Class<TEntity> entityClass,
                                  de.xima.cmn.criteria.SelectCriterion selectCriterion,
                                  ISerializablePredicate<javax.persistence.Tuple> tuplePredicate)

Creates a new filter criteria supplier with a single select criterion. Lets you specify a filter predicate with custom Java logic that is applied to each existing entity. This supplier creates a filter that matches only entities that satisfy the given predicate.

Parameters:

key - Key for equating different criteria suppliers.

entityClass - Type of the entity to which the filter criteria are applied.

selectCriterion - Select criterion for the entity attribute to select.

tuplePredicate - Predicate for the entities to match, each tuple represents an entity containing the attributes from the given select criteria.
