Interface IPagedListIterator<T>

All Superinterfaces

Iterator<T>, ListIterator<T>, Serializable

public interface IPagedListIterator<T>
extends ListIterator<T>, Serializable

A bi-directional iterator for traversing query results in a read-only manner. This iterator does not support changing the collection results in any manner.

An overview of PagedList capabilities, including sorting and filtering, is provided in the package documentation at com.bea.content.paging

Changes to the collection should be made via the CM APIs such as com.bea.content.federated.INodeManager, and the query should be re-issued.

NOTE: items returned from this iterator should not be modified, since for performance reasons they are lightweight objects which can be re-used by other iterators. Use the interfaces INodeManager, ITypeManager, etc. to make changes to the backing store.

This interface is intended to be implemented only by Oracle Weblogic Portal. Oracle Systems reserves the right to add abstract methods to this interface without notice. Implementations of this interface by other parties must not be expected to compile without change in future versions of Oracle Weblogic Portal.
