Examples of org.atmosphere.wasync.Client

org.atmosphere.wasync.Client

An asynchronous client's implementation used to create {@link Socket} and {@link Request}. As simple as as

 Client client = ClientFactory.getDefault().newClient(); RequestBuilder request = client.newRequestBuilder() .method(Request.METHOD.GET) .uri(targetUrl + "/suspend") .decoder(new Decoder<String, POJO>() { @Override public POJO decode(String s) { return new POJO(s); } }) .transport(Request.TRANSPORT.WEBSOCKET);
