java.lang.Object org.nuxeo.ecm.core.storage.sql.SelectionContext
public class SelectionContext
A SelectionContext
holds information for a set Selection
objects, mostly acting as a cache.
Some of the information is identical to what's in the database and can be safely be GC'ed, so it lives in a memory-sensitive map (softMap), otherwise it's moved to a normal map (hardMap) (creation or deletion).

invalidate
- true
if this is for a fragment newly created by
internal database process (copy, etc.) and must notified to
other session; false
if this is a normal read

StorageException
public SimpleFragment getSelectionFragment(Serializable selId, String filter) throws StorageException
If the fragment is not in the context, fetch it from the mapper.
selId
- the selection idfilter
- the value to filter on
null
if not found
StorageException

No sorting on value is done.
selId
- the selection idfilter
- the value to filter on, or null
for all
StorageException
public void postSave()
public void markInvalidated(Set<RowId> modified)
Mapper
operation (like a version restore).
public void gatherInvalidations(Invalidations invalidations)
Called post-transaction to gathers invalidations to be sent to others.
