DatabaseConnection class
A database connection managed by drift. Contains three components:
- a SqlTypeSystem, which is responsible to map between Dart types and values understood by the database engine.
- a QueryExecutor, which runs sql commands
- a
StreamQueryStore, which dispatches table changes to listening queries, on which the auto-updating queries are based.
Constructors
- DatabaseConnection(SqlTypeSystem typeSystem, QueryExecutor executor, StreamQueryStore streamQueries)
- Constructs a raw database connection from the three components.
-
DatabaseConnection.delayed(FutureOr<
DatabaseConnection> connection) -
Database connection that is instantly available, but delegates work to a
connection only available through a
Future.factory - DatabaseConnection.fromExecutor(QueryExecutor executor)
-
Constructs a DatabaseConnection from the QueryExecutor by using the
default type system and a new
StreamQueryStore.
