Interface ServerSocket

All Superinterfaces:

AbstractServerSocket<ServerSocket>

public interface ServerSocket
extends AbstractServerSocket<ServerSocket>

Interface used to interact with the remote socket.

ServerSocket produced by Server is used to send and receive event to and from the remote socket. The normal usage to use ServerSocket is to create a socket action and pass it to Server. If you are going to hold a reference on ServerSocket, you should do something when it is closed through onclose(Action).

Sockets may be accessed by multiple threads.

Method Detail

uri

String uri()

A URI used to connect. To work with URI parts, use URI or something like that.

tags

Set<String> tags()

A modifiable set of tag names.

on

<T> ServerSocket on(String event,
                  io.cettia.platform.action.Action<T> action)

Adds a given event handler for a given event.

The allowed types for T are Java types corresponding to JSON types.

JSON	Java
Number	Integer or Double
String	String
Boolean	Boolean
Array	List, List<T> in generic
Object	Map, Map<String, T> in generic
null	null, Void for convenience

If the counterpart sends an event with callback, T should be ServerSocket.Reply.

onclose

ServerSocket onclose(io.cettia.platform.action.Action<Void> action)

Executed if the socket is closed for any reason. Equivalent to socket.on("close", action)

onerror

ServerSocket onerror(io.cettia.platform.action.Action<Throwable> action)

Executed if there was any error on the socket. You don't need to close it explicitly on error event. Equivalent to socket.on("error", action)

off

<T> ServerSocket off(String event,
                   io.cettia.platform.action.Action<T> action)

Removes a given event handler for a given event.

send

<T> ServerSocket send(String event,
                    Object data,
                    io.cettia.platform.action.Action<T> resolved)

Sends a given event with data attaching resolved callback.

For the allowed types for T, see on(String, Action).

send

<T,U> ServerSocket send(String event,
                      Object data,
                      io.cettia.platform.action.Action<T> resolved,
                      io.cettia.platform.action.Action<U> rejected)

Sends a given event with data attaching resolved callback and rejected callback.

For the allowed types for T, see on(String, Action).

unwrap

<T> T unwrap(Class<T> clazz)

Returns the underlying component. ServerTransport is available.
