org.alfresco.repo.domain.contentdata.AbstractContentDataDAOImpl

All Implemented Interfaces:

ContentDataDAO

Direct Known Subclasses:

ContentDataDAOImpl

public abstract class AbstractContentDataDAOImpl
extends Object
implements ContentDataDAO

Abstract implementation for ContentData DAO.

This provides basic services such as caching, but defers to the underlying implementation for CRUD operations.

The DAO deals in ContentData instances. The cache is primarily present to decode IDs into ContentData instances.

public AbstractContentDataDAOImpl()

Default constructor

Method Detail

setControlDAO

public void setControlDAO(ControlDAO controlDAO)

Parameters:

controlDAO - create Savepoints

setMimetypeDAO

public void setMimetypeDAO(MimetypeDAO mimetypeDAO)

setEncodingDAO

public void setEncodingDAO(EncodingDAO encodingDAO)

setLocaleDAO

public void setLocaleDAO(LocaleDAO localeDAO)

setContentStoreCleaner

public void setContentStoreCleaner(EagerContentStoreCleaner contentStoreCleaner)

Set this property to enable eager cleanup of orphaned content.

Parameters:

contentStoreCleaner - an eager cleaner (may be null)

setContentDataCache

public void setContentDataCache(org.alfresco.repo.cache.SimpleCache<Long,org.alfresco.service.cmr.repository.ContentData> contentDataCache)

Parameters:

contentDataCache - the cache of IDs to ContentData and vice versa

registerDereferencedContentUrl

protected void registerDereferencedContentUrl(String contentUrl)

A content_url entity was dereferenced. This makes no assumptions about the current references - dereference deletion is handled in the commit phase.

createContentData

public org.alfresco.util.Pair<Long,org.alfresco.service.cmr.repository.ContentData> createContentData(org.alfresco.service.cmr.repository.ContentData contentData)

Create a new ContentData instance.

Specified by:

createContentData in interface ContentDataDAO

Parameters:

contentData - the ContentData details

the ContentData pair (id, ContentData) (never null)

getContentData

public org.alfresco.util.Pair<Long,org.alfresco.service.cmr.repository.ContentData> getContentData(Long id)

Specified by:

getContentData in interface ContentDataDAO

Parameters:

id - the unique ID of the entity

Returns:

the ContentData pair (id, ContentData) or null if it doesn't exist

cacheContentDataForNodes

public void cacheContentDataForNodes(Set<Long> nodeIds)

Specified by:

cacheContentDataForNodes in interface ContentDataDAO

Parameters:

nodeIds - the nodeIds

updateContentData

public void updateContentData(Long id,
                     org.alfresco.service.cmr.repository.ContentData contentData)

Update a content data instance
