Method Detail

getKey

public Serializable getKey()

Generate the unique caching key. This key must be unique inside the space of this component.

Specified by:

getKey in interface org.apache.cocoon.caching.CacheableProcessingComponent

getValidity

public org.apache.excalibur.source.SourceValidity getValidity()

Generate the cache validity object. The validity object all recently submitted items. This does not include the community / collection hierarchy, when this changes they will not be reflected in the cache.

Specified by:

getValidity in interface org.apache.cocoon.caching.CacheableProcessingComponent

getRecentlySubmittedItems

protected void getRecentlySubmittedItems(DSpaceObject dso)

Retrieves the recent submitted items of the given scope

Parameters:

dso - the DSpace object can either be null (indicating home page), a collection or a community

recycle

public void recycle()

Specified by:

recycle in interface org.apache.avalon.excalibur.pool.Recyclable

Overrides:

recycle in class AbstractDSpaceTransformer
