setMimetypeEntityCache

public void setMimetypeEntityCache(org.alfresco.repo.cache.SimpleCache<Serializable,Serializable> mimetypeEntityCache)

public org.alfresco.util.Pair<Long,String> getMimetype(Long id)

Specified by:

getMimetype in interface MimetypeDAO

Parameters:

id - the unique ID of the entity

Returns:

the Mimetype pair (id, mimetype) (never null)

getMimetype

public org.alfresco.util.Pair<Long,String> getMimetype(String mimetype)

Specified by:

getMimetype in interface MimetypeDAO

Parameters:

mimetype - the Mimetype to query for

Returns:

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

getOrCreateMimetype

public org.alfresco.util.Pair<Long,String> getOrCreateMimetype(String mimetype)

Description copied from interface: MimetypeDAO

Retrieve an existing mimetype or create a new one if it doesn't exist.

Specified by:

getOrCreateMimetype in interface MimetypeDAO

Parameters:

mimetype - the Mimetype

updateMimetype

public int updateMimetype(String oldMimetype,
                 String newMimetype)

Description copied from interface: MimetypeDAO

Update a mimetype if it exists. This method does not do any conflict resolution i.e. it will only succeed if the new mimetype does not exist already. Higher-level logic is required to handle updates to dependent rows, etc.

Specified by:

Parameters:

oldMimetype - the old Mimetype

newMimetype - the new Mimetype

Returns:

the number of rows modified

getMimetypeEntity

protected abstract MimetypeEntity getMimetypeEntity(Long id)

Parameters:

id - the ID of the mimetype entity

Returns:

Return the entity or null if it doesn't exist

getMimetypeEntity

protected abstract MimetypeEntity getMimetypeEntity(String mimetype)

createMimetypeEntity

updateMimetypeEntity

protected abstract int updateMimetypeEntity(Long id,
                       String newMimetype)
