Examples with Decoder javax.websocket.Decoder used on opensource projects

Example 1 with Decoder

use of javax.websocket.Decoder in project tomcat by apache.

        } else {
            byte[] array = new byte[message.limit() - message.position()];
            message.get(array);
            ByteArrayInputStream bais = new ByteArrayInputStream(array);
            try {
                return ((BinaryStream<?>) decoder).decode(bais);
            } catch (IOException ioe) {
                throw new DecodeException(message, sm.getString("pojoMessageHandlerWhole.decodeIoFail"), ioe);
            }
        }
    }
    return null;
}

Example 2 with Decoder

use of javax.websocket.Decoder in project che by eclipse.

    final List<Class<? extends Decoder>> decoders = new LinkedList<>();
    encoders.add(OutputMessageEncoder.class);
    decoders.add(InputMessageDecoder.class);
    final ServerEndpointConfig endpointConfig = create(CheWSConnection.class, websocketContext + websocketEndPoint).configurator(createConfigurator()).encoders(encoders).decoders(decoders).build();
    endpointConfig.getUserProperties().put(EVERREST_PROCESSOR_ATTRIBUTE, getEverrestProcessor(servletContext));

                } else {
                    throw new InvalidWebSocketException("PathParam decoders must use Decoder.Text");
                }
            }
        }
    }
