- the type of the entity persisted in this container (which must be the entity's concrete type -
not the root-type of the inheritance tree!). See getClassMeta()
for further details.keyStoreRefID
- TODOobjectID
- the String
-representation of the entity's identifier (aka OID or object-ID).

public long getDataEntryID()
DataEntry
.
public ClassMeta getClassMeta()
Get the type of the entity persisted in this container.
Note, that this is the concrete type of the persisted object and not the root-type of the
persistable hierarchy. For example, if bbb
is persisted and bbb
is an instance of
class BBB
which extends AAA
and both classes are persistable, this will point to class BBB
(and not AAA
).
Therefore, if you want to query all instances of a certain type including subclasses, you have to
ask for the sub-classes via StoreManager.getSubClassesForClass(String, boolean, org.datanucleus.ClassLoaderResolver)
first and then query for all these classes individually.
