Interface Version

All Superinterfaces:

DeltaVItem, HierarchyItem

public interface Version
extends DeltaVItem

Represents single item version.

Defines the properties and methods that item version must implement. In addition to methods and properties provided by DeltaVItem this interface also provides methods for getting version name, next version and previous version.

Usually you will implement Version interface for your resource version objects together with File interface. While Resource interface is optional for resource versions it may be useful if your DeltaV client application will request content of the resource version. In this case File.read(java.io.OutputStream, long, long), File.getContentLength() and File.getContentType() members of the File interface will be requested by the engine. Copying, moving, updating properties and content are not allowed for a version, your HierarchyItem.copyTo(com.ithit.webdav.server.Folder, java.lang.String, boolean), HierarchyItem.moveTo(com.ithit.webdav.server.Folder, java.lang.String), HierarchyItem.updateProperties(com.ithit.webdav.server.Property[], com.ithit.webdav.server.Property[]) and File.write(java.io.InputStream, java.lang.String, long, long) implementations must throw ServerException with status WebDavStatus.NOT_ALLOWED
