Class AbstractQueryPage<T>

java.lang.Object

org.beangle.commons.collection.page.PageWapper<T>

org.beangle.commons.dao.query.limit.AbstractQueryPage<T>

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>, Page<T>

Direct Known Subclasses:

QueryPage

public abstract class AbstractQueryPage<T>
