Elemental2 is just the browsers API so pretty much any javascript example
will work. As a matter of fact, I always used to annoy/delight some of my
colleagues by taking an ES6 example and search replacing "const" with
"var", "let" with "var" and "=>" with "->" and you would be amazed how
often this produced workable code after a few autoimport fixes.
Anyhoo ... something like the following will work although I have not
compiled or tested this ... it is just a translation of a javascript
example ;).
final WebSocket socket = new WebSocket( "wss://echo.websocket.org/" );
socket.onopen = e -> {
DomGlobal.console.log( "[open] Connection established" );
socket.send( Global.JSON.stringify( JsPropertyMap.of( "message","Hi
ho Silver!" ) ) );
};
socket.onerror = e -> DomGlobal.console.log( "[error]", e );
socket.onmessage = e -> DomGlobal.console.log( "[message] Data
received from server: ", e.data );
socket.onclose = e -> {
if ( e.wasClean )
{
DomGlobal.console.log( "[close] Connection closed cleanly, code="
+ e.code + " reason=" + e.reason + "" );
}
else
{
// e.g. server process killed or network down
// event.code is usually 1006 in this case
DomGlobal.console.log( "[close] Connection died" );
}
};
