Method Detail

getDelegate

public io.vertx.pgclient.PgConnection getDelegate()

Overrides:

getDelegate in class SqlConnection

connect

public static io.smallrye.mutiny.Uni<PgConnection> connect(Vertx vertx,
                                                           io.vertx.pgclient.PgConnectOptions options)

Connects to the database and returns the connection if that succeeds.

The connection interracts directly with the database is not a proxy, so closing the connection will close the underlying connection to the database.

Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.

Parameters:

vertx - the vertx instance

options - the connect options

Returns:

the uni firing the result of the operation when completed, or a failure if the operation failed.

connectAndAwait

public static PgConnection connectAndAwait(Vertx vertx,
                                           io.vertx.pgclient.PgConnectOptions options)

Blocking variant of connect(io.vertx.mutiny.core.Vertx,PgConnectOptions).

This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

Parameters:

vertx - the vertx instance

options - the connect options

Returns:

the PgConnection instance produced by the operation.

connectAndForget

public static void connectAndForget(Vertx vertx,
                                    io.vertx.pgclient.PgConnectOptions options)

Variant of connect(io.vertx.mutiny.core.Vertx,PgConnectOptions) that ignores the result of the operation.

This method subscribes on the result of connect(io.vertx.mutiny.core.Vertx,PgConnectOptions), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from connect(io.vertx.mutiny.core.Vertx,PgConnectOptions) but you don't need to compose it with other operations.

Parameters:

vertx - the vertx instance

options - the connect options

connect

Parameters:

vertx -

Returns:

the uni firing the result of the operation when completed, or a failure if the operation failed.

connectAndAwait

public static PgConnection connectAndAwait(Vertx vertx)

Blocking variant of connect(io.vertx.mutiny.core.Vertx).

This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

Parameters:

vertx -

Like connect(io.vertx.mutiny.core.Vertx, io.vertx.pgclient.PgConnectOptions) with options build from connectionUri.

Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.
