Examples of org.glassfish.tyrus.spi.Writer

org.glassfish.tyrus.spi.Writer
Writer class that is used by tyrus runtime to pass outbound websocket data for a connection to a transport. Then, the transport actually writes the data eventually.
A transport creates implementation of this class and registers the writer object using {@link WebSocketEngine.UpgradeInfo#createConnection} aftera successful upgrade. @author Pavel Bucek (pavel.bucek at oracle.com)
