Method Detail
-
startProcessing
void startProcessing()
Informs the processor the start of the process. The processor use this method to allocate all the resources required by the processing here. It uses it to initialize the processor state machine.
-
endProcessing
void endProcessing()
Informs the processor the process is ended. The processor use this method to deallocate all the resources that were used during the processing. It uses it to tear down the processor state machine or to finalize some treatments. The processing has to stop once this method is called. Hence, the call of process methods should result to nothing or to an exception.

then
MediaCriteriaProcessor then()
Informs the processor that there is a new criterion to process. This method must be used by the caller to chain the different criterion processings.- Returns:
- the processor itself.
-
processResultLimit
MediaCriteriaProcessor processResultLimit(int resultLimit)
Processes the criterion on the media result limit.- Parameters:
resultLimit
- the limit of the result (0 = no limit)- Returns:
- the processor itself.
-
processVisibility
MediaCriteriaProcessor processVisibility(MediaCriteria.VISIBILITY visibility, Date dateReference, org.silverpeas.core.admin.user.model.UserDetail creator)
Processes the criterion on the media visibility.- Parameters:
visibility
- the requested visibility.dateReference
-creator
- User Detail- Returns:
- the processor itself.
-
processIdentifiers
MediaCriteriaProcessor processIdentifiers(List<String> identifiers)
Processes the criterion on the media identifiers.- Parameters:
identifiers
- the media identifiers concerned by the criterion.- Returns:
- the processor itself.
-
processComponentInstance
MediaCriteriaProcessor processComponentInstance(String componentInstanceId)
Processes the criterion on the component instance identifier.- Parameters:
componentInstanceId
- the identifier of the component instance concerned by the criterion.- Returns:
- the processor itself.
-
processAlbums
MediaCriteriaProcessor processAlbums(List<String> albumIds)
Processes the criterion on the identifiers of albums (Actually, Album = Node).- Parameters:
albumIds
- the identifiers of albums concerned by the criterion.- Returns:
- the processor itself.
-
processCreator
MediaCriteriaProcessor processCreator(org.silverpeas.core.admin.user.model.UserDetail creator)
Processes the criterion on the creator of the medias.- Parameters:
creator
- the user concerned by the criterion.- Returns:
- the processor itself.
-
processMediaTypes
MediaCriteriaProcessor processMediaTypes(List<MediaType> mediaTypes)
Processes the criterion on type of media.- Parameters:
mediaTypes
- the media types concerned by the criterion.- Returns:
- the processor itself.
-
processNbDaysBeforeThatMediaIsNotVisible
MediaCriteriaProcessor processNbDaysBeforeThatMediaIsNotVisible(Date referenceDate, int nbDaysBeforeThatMediaIsNotVisible)
Processes the criterion on the nb of days before that a media is not visible.- Parameters:
referenceDate
-nbDaysBeforeThatMediaIsNotVisible
- the nb of days before that a media is not visible.- Returns:
- the processor itself.
-
processOrdering
MediaCriteriaProcessor processOrdering(List<MediaCriteria.QUERY_ORDER_BY> orderings)
Processes the criterion on orderings of the medias matching the criteria.- Parameters:
orderings
- the result orderings concerned by the criterion.- Returns:
- the processor itself.
-
result
<T> T result()
Gets the result of the processing. Warning, the result can be incomplete if called before the processing ending (triggered with the call ofendProcessing()
method).- Type Parameters:
T
- the type of the result.- Returns:
- the processing result.
