Interface NetClient

All Superinterfaces:

Measured

public interface NetClient
extends Measured

A TCP client.

Multiple connections to different servers can be made using the same instance.

This client supports a configurable number of connection attempts and a configurable delay between attempts.

Method Detail

connect

NetClient connect(int port,
                  String host,
                  Handler<AsyncResult<NetSocket>> connectHandler)

Open a connection to a server at the specific port and host.

host can be a valid host name or IP address. The connect is done asynchronously and on success, a NetSocket instance is supplied via the connectHandler instance

Parameters:

port - the port

host - the host

Returns:

a reference to this, so the API can be used fluently

connect

Future<NetSocket> connect(int port,
                          String host)

Like connect(int, String, Handler) but returns a Future of the asynchronous result

connect

NetClient connect(int port,
                  String host,
                  String serverName,
                  Handler<AsyncResult<NetSocket>> connectHandler)

Open a connection to a server at the specific port and host.

host can be a valid host name or IP address. The connect is done asynchronously and on success, a NetSocket instance is supplied via the connectHandler instance

Parameters:

port - the port

host - the host

serverName - the SNI server name

Returns:

a reference to this, so the API can be used fluently

connect

Future<NetSocket> connect(int port,
                          String host,
                          String serverName)

Like connect(int, String, String, Handler) but returns a Future of the asynchronous result

connect

NetClient connect(SocketAddress remoteAddress,
                  Handler<AsyncResult<NetSocket>> connectHandler)

Open a connection to a server at the specific remoteAddress.

The connect is done asynchronously and on success, a NetSocket instance is supplied via the connectHandler instance

Parameters:

remoteAddress - the remote address

Returns:

a reference to this, so the API can be used fluently

connect

Future<NetSocket> connect(SocketAddress remoteAddress)

Like connect(SocketAddress, Handler) but returns a Future of the asynchronous result

connect

NetClient connect(SocketAddress remoteAddress,
                  String serverName,
                  Handler<AsyncResult<NetSocket>> connectHandler)

Open a connection to a server at the specific remoteAddress.

The connect is done asynchronously and on success, a NetSocket instance is supplied via the connectHandler instance

Parameters:

remoteAddress - the remote address

serverName - the SNI server name

Returns:

a reference to this, so the API can be used fluently

connect

Future<NetSocket> connect(SocketAddress remoteAddress,
                          String serverName)

Like connect(SocketAddress, String, Handler) but returns a Future of the asynchronous result

close

void close(Handler<AsyncResult<Void>> handler)

Close the client.

Any sockets which have not been closed manually will be closed here. The close is asynchronous and may not complete until some time after the method has returned.

close

Future<Void> close()

Like close(Handler) but returns a Future of the asynchronous result

updateSSLOptions

Future<Void> updateSSLOptions(SSLOptions options)

Update the client SSL options. Update only happens if the SSL options is valid.

Parameters:

options - the new SSL options

Returns:

a future signaling the update success

updateSSLOptions

default void updateSSLOptions(SSLOptions options,
                              Handler<AsyncResult<Void>> handler)

Like updateSSLOptions(SSLOptions) but supplying a handler that will be called when the update happened (or has failed).

Parameters:

options - the new SSL options

handler - the update handler
