Class AbstractCriterionGroup<T extends PersistentEntityCriterion<V>,V>

java.lang.Object
  com.anasoft.os.daofusion.util.SimpleListContainer<T>
      com.anasoft.os.daofusion.criteria.AbstractCriterionGroup<T,V>

Type Parameters:

T - Type of the criterion managed by the group.

V - Type of the criterion visitor applicable for managed criterion instances.

All Implemented Interfaces:

PersistentEntityCriteria

Direct Known Subclasses:

NestedPropertyCriteria

public abstract class AbstractCriterionGroup<T extends PersistentEntityCriterion<V>,V>
extends SimpleListContainer<T>
implements PersistentEntityCriteria

Base class for persistent entity criteria implementations working with PersistentEntityCriterion instances.

This class defines the contract for paging criteria (firstResult and maxResults) as well as its application to the target Criteria instance.
