Creates an index queryable via the primary key. This is called *after* the entity this association indexer is part of has been persisted. Usually, for a particular association type, only this OR preIndex(Object, java.util.List) will be implemented.

primaryKey - The primaryKeyforeignKey - The foreignKeyCreates an index queryable via the primary key. This is called *before* the entity that this association indexer is part of is persisted, but after the native entry has been updated ready to be persisted. This allows the index to be placed in the native instance itself, e.g. in a document database. Usually, for a particular association type, only this OR index(Object, java.util.List) will be implemented.
