Class LazyBeanList

java.lang.Object

de.innovationgate.webgate.api.templates.LazyBeanList

All Implemented Interfaces:

WGResultSetCore, java.lang.Iterable, java.util.Collection, java.util.List

public class LazyBeanList
extends java.lang.Object
implements java.util.List, WGResultSetCore

Implements a "lazy" list of retrieved beans. This list can first be filled with the keys of beans. When beans are used, they are retrieved by their keys automatically. However beans that never get used will not be retrieved, saving performance and resources.

Returns:

List of contents. Empty list if this result set holds no content.

isReturnsKeys

public boolean isReturnsKeys()

Description copied from interface: WGResultSetCore

Determines, if this result set core only returns WGContentKey-Objects, to allow the WGAPI to rely on cached document objects. If false, this result set core is expected to return WGDocumentCore objects.

Specified by:
