transactionTimestamp :: Transaction -> UTCTime

transactionParentIds :: Transaction -> Set TransactionId

transactionChildIds :: Transaction -> Set TransactionId

transactionSetChildren :: Transaction -> Set TransactionId -> Transaction

Create a new transaction which is identical to the original except that a new set of child transaction ids is added.

filterTransactionInfoTransactions :: Set TransactionId -> TransactionInfo -> TransactionInfo

Return the same transaction but referencing only the specific child transactions. This is useful when traversing a graph and returning a subgraph. This doesn't filter parent transactions because it assumes a head-to-root traversal.

filterParent :: TransactionId -> Set TransactionId -> TransactionId

filterTransaction :: Set TransactionId -> Transaction -> Transaction

Remove any child or parent transaction references not in the valud UUID set.

concreteDatabaseContext :: Transaction -> DatabaseContext

Return the singular context which is not virtual.

schemas :: Transaction -> Schemas

Returns all schemas including the concrete schema.

subschemas :: Transaction -> Subschemas

Returns all subschemas which are isomorphic or sub-isomorphic to the concrete schema.
