Package org.apache.openjpa.lib.rop

Result Object Provider Framework

This package provides a framework for the lazy loading of potentially large lists of data.

Interface Summary

Interface	Description
BatchedResultObjectProvider	A provider for multiple result sets.
ResultList<E>	List interface that represents a potentially lazy ResultList instantiation.
ResultObjectProvider	Interface that allows lazy/custom instantiation of input objects.

Class Summary

Class	Description
AbstractNonSequentialResultList	Abstract base class for random-access result lists.
AbstractResultList<E>	Abstract base class for read-only result lists.
AbstractSequentialResultList	Abstract base class for sequential result lists.
EagerResultList	Simple, non-lazy ResultList implementation
LazyForwardResultList	Lazy forward-only result list.
ListResultList	A basic ResultList implementation that wraps a normal list.
ListResultObjectProvider	A result object provider wrapped around a normal list.
MergedResultObjectProvider	A result object provider that merges multiple result object provider delegates.
RandomAccessResultList	Random-access result list implementation.
RangeResultObjectProvider	Prevents a view of a given range of indices from the delegate result object provider.
ResultListIterator	Wrapper iterator that will return false for hasNext() if the owning ResultList has been closed.
ResultObjectProviderIterator	Iterator wrapped around a ResultObjectProvider.
SimpleResultList	An almost stateless ResultList designed for use with result object providers backed by efficient random-access data structures, such as the ListResultObjectProvider.
SoftRandomAccessResultList	Specialization of the RandomAccessResultList that only maintains soft references to instantiated objects.
WindowResultList	ResultList implementation that uses a forward-scrolling window of results.
