Constructor Detail

AbstractWebSocketSession

protected AbstractWebSocketSession(T delegate,
                                   String id,
                                   HandshakeInfo info,

Create a new WebSocket session.

Method Detail

getDelegate

protected T getDelegate()

getId

public String getId()

Description copied from interface: WebSocketSession

Return the id for the session.

Specified by:

getId in interface WebSocketSession

getHandshakeInfo

public HandshakeInfo getHandshakeInfo()

Description copied from interface: WebSocketSession

Return information from the handshake request.

Specified by:

getHandshakeInfo in interface WebSocketSession

bufferFactory

public DataBufferFactory bufferFactory()

Description copied from interface: WebSocketSession

Return a DataBuffer Factory to create message payloads.

Specified by:

bufferFactory in interface WebSocketSession

Returns:

the buffer factory for the session

getAttributes

public Map<String,Object> getAttributes()

Description copied from interface: WebSocketSession

Return the map with attributes associated with the WebSocket session.

Specified by:

getAttributes in interface WebSocketSession

Returns:

a Map with the session attributes (never null)

getLogPrefix

protected String getLogPrefix()

receive

public abstract reactor.core.publisher.Flux<WebSocketMessage> receive()

Description copied from interface: WebSocketSession

Provides access to the stream of inbound messages.

This stream receives a completion or error signal when the connection is closed. In a typical WebSocketHandler implementation this stream is composed into the overall processing flow, so that when the connection is closed, handling will end.

See the class-level doc of WebSocketHandler and the reference for more details and examples of how to handle the session.

Specified by:

receive in interface WebSocketSession

send

public abstract reactor.core.publisher.Mono<Void> send(org.reactivestreams.Publisher<WebSocketMessage> messages)

Description copied from interface: WebSocketSession

Give a source of outgoing messages, write the messages and return a Mono<Void> that completes when the source completes and writing is done.

See the class-level doc of WebSocketHandler and the reference for more details and examples of how to handle the session.

Specified by:

send in interface WebSocketSession

textMessage

public WebSocketMessage textMessage(String payload)

Description copied from interface: WebSocketSession

Factory method to create a text WebSocketMessage using the WebSocketSession.bufferFactory() for the session.

Specified by:

textMessage in interface WebSocketSession

binaryMessage

public WebSocketMessage binaryMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)

Description copied from interface: WebSocketSession

Factory method to create a binary WebSocketMessage using the WebSocketSession.bufferFactory() for the session.

Specified by:

binaryMessage in interface WebSocketSession

pingMessage

public WebSocketMessage pingMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)

Description copied from interface: WebSocketSession

Factory method to create a ping WebSocketMessage using the WebSocketSession.bufferFactory() for the session.

Specified by:

pingMessage in interface WebSocketSession

pongMessage

public WebSocketMessage pongMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)

Description copied from interface: WebSocketSession

Factory method to create a pong WebSocketMessage using the WebSocketSession.bufferFactory() for the session.

Specified by:

pongMessage in interface WebSocketSession

toString

public String toString()

Overrides:

toString in class Object
