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

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

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

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

close

void close()

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.
