@Deprecated
public class ContentServiceImpl
extends Object
implements ContentService, ChangeGenerator<Object[]>

An implementation of the default ContentService
This class will also generate Event with are Object[]

Since this implements ChangeGenerator; it will also generate Events of Type

• Object[]{"save", content}
• Object[]{"new-content", content, sequence as Integer}
• Object[]{"publish", published-content, source-content, path as String}
• Object[]{"unpublish", content, published path as String}
• Object[]{"move", content, newParent, sequence as Integer, movedRelatedContent as Map<Status, ContentDescriber>}

• Object[]{"delete-subhierarchy", node as ContentDescriber}
• Object[]{"after-delete", name}
• Object[]{"save-facet", ContentFacet}

HierarchyContentSource Override for event generation

This will cause an update to the Content state. Note, it is the responsibility of the calling API to ensure that the content status is not conflicting with an existing state.

For example: If a content (for the locale) is in status Status.DRAFT, and is being updated to Status.PUBLISH while another Status.PUBLISH one already exists. Then it should update the PUBLISH record for the content and mute the Status.DRAFT one (in concept).

Specified by:

updateContentStatus in interface GenericContentService<ContentDescriber,ContentAttribute,ContentFacet>

Parameters:

name - as identifier for the content

locale - as the Locale

oldStatus - as the Status

newStatus - as the Status (replace the oldStatus with this value)

Returns:

int as number of rows updated

Throws:

Exception
