.delete_orphans ⇒ Number

Delete orphan marks

Marks are deleted when marker or markable record is destroyed. However, in some circumstances, some marks may reference non existing records (for instance if the record has been deleted - not destroyed).

Note: this method is not efficient but this should not be a problem as it should be used as a maintenance operation only.

Returns:

  • (Number) —

    Deleted orphan marks count
