Wraps objects of the DBIDriver class to include connection options. The purpose of this class is to store both the driver and the connection options. A database connection can be established with a call to dbConnect(), passing only that object without additional arguments.

Details

To prevent leakage of passwords and other credentials, this class supports delayed evaluation. All arguments can optionally be a function (callable without arguments). In such a case, the function is evaluated transparently when connecting in dbGetConnectArgs().

# Create a connector: cnr <- new("DBIConnector", .drv = RSQLite::SQLite(), .conn_args = list(dbname = ":memory:") ) cnr
#> <DBIConnector><SQLiteDriver> #> Arguments: #> $dbname #> [1] ":memory:" #>
# Establish a connection through this connector: con <- dbConnect(cnr) con
#> <SQLiteConnection> #> Path: :memory: #> Extensions: TRUE
# Access the database through this connection: dbGetQuery(con, "SELECT 1 AS a")
#> a #> 1 1
