java.lang.Objectorg.cumulus4j.store.model.IndexEntryObjectRelationHelper
public class IndexEntryObjectRelationHelper
Helper to find an IndexEntry
for an object relation (1-1, 1-n or m-n).
Even though DefaultIndexEntryFactory
and IndexEntryLong
are used for such relations, these
classes should not be directly accessed in order to make refactorings easier (if this class is used for all
object relations, it is possible to search for references of this class).

public static IndexEntryFactory getIndexEntryFactory()
public static List<IndexEntry> getIndexEntriesIncludingSubClasses(CryptoContext cryptoContext, PersistenceManager pmIndex, FieldMeta fieldMeta, ClassMeta classMeta, Long indexedDataEntryID)
public static List<IndexEntry> getIndexEntries(CryptoContext cryptoContext, PersistenceManager pmIndex, FieldMeta fieldMeta, List<ClassMeta> classMetas, Long indexedDataEntryID)
public static IndexEntry getIndexEntry(CryptoContext cryptoContext, PersistenceManager pmIndex, FieldMeta fieldMeta, ClassMeta classMeta, Long indexedDataEntryID)
IndexEntry
or null
, if it does not exist.
This method looks up an IndexEntry
for a relation to the object referenced
by the given indexedDataEntryID
and the relation-type specified by the given fieldMeta
.
cryptoContext
- the crypto-context.pmIndex
- the backend-PersistenceManager
used to access the index-datastore.fieldMeta
- the field pointing to the referenced object.classMeta
- the concrete owner type holding the field (might be a sub-class of fieldMeta.classMeta
.indexedDataEntryID
- the DataEntry.dataEntryID
of the referenced object.
IndexEntry
or null
.public static IndexEntry createIndexEntry(CryptoContext cryptoContext, PersistenceManager pmIndex, FieldMeta fieldMeta, ClassMeta classMeta, Long indexedDataEntryID)
IndexEntry
or create it, if it does not yet exist. This method behaves
just like getIndexEntry(CryptoContext, PersistenceManager, FieldMeta, ClassMeta, Long)
, but instead of returning null
,
it creates an IndexEntry
, if it does not yet exist.
cryptoContext
- the crypto-context.pmIndex
- the backend-PersistenceManager
used to access the index-datastore.fieldMeta
- the field pointing to the referenced object.classMeta
- the concrete owner type holding the field (might be a sub-class of fieldMeta.classMeta
.indexedDataEntryID
- the DataEntry.dataEntryID
of the referenced object.
IndexEntry
; never null
