public interface PgConnection extends SqlConnection
The connection object supports all the operations defined in the SqlConnection interface,
it also provides additional support:
| Modifier and Type | Method and Description |
|---|---|
PgConnection |
cancelRequest(io.vertx.core.Handler<io.vertx.core.AsyncResult<Void>> handler)
Send a request cancellation message to tell the server to cancel processing request in this connection.
|
static PgConnection |
cast(SqlConnection sqlConnection)
Cast a
SqlConnection to PgConnection. |
PgConnection |
closeHandler(io.vertx.core.Handler<Void> handler) |
static io.vertx.core.Future<PgConnection> |
connect(io.vertx.core.Vertx vertx)
Like
connect(Vertx, Handler) but returns a Future of the asynchronous result |
static void |
connect(io.vertx.core.Vertx vertx,
io.vertx.core.Handler<io.vertx.core.AsyncResult<PgConnection>> handler)
Like
connect(Vertx, PgConnectOptions, Handler) with options build from the environment variables. |
static io.vertx.core.Future<PgConnection> |
connect(io.vertx.core.Vertx vertx,
PgConnectOptions options)
Like
connect(Vertx, PgConnectOptions, Handler) but returns a Future of the asynchronous result |

PgConnectOptions options,
io.vertx.core.Handler<io.vertx.core.AsyncResult<PgConnection>> handler)
Connects to the database and returns the connection if that succeeds.
|
static io.vertx.core.Future<PgConnection> |
connect(io.vertx.core.Vertx vertx,

connect(io.vertx.core.Vertx vertx,
String connectionUri,
io.vertx.core.Handler<io.vertx.core.AsyncResult<PgConnection>> handler)
