Documentation
transactionSetChildren :: Transaction -> Set TransactionId -> Transaction Source #
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 Source #
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.
filterTransaction :: Set TransactionId -> Transaction -> Transaction Source #
Remove any child or parent transaction references not in the valud UUID set.
concreteDatabaseContext :: Transaction -> DatabaseContext Source #
Return the singular context which is not virtual.
schemas :: Transaction -> Schemas Source #
Returns all schemas including the concrete schema.
subschemas :: Transaction -> Subschemas Source #
Returns all subschemas which are isomorphic or sub-isomorphic to the concrete schema.
