WebSocketSession (Spring Framework 5.3.1 API)

All Known Implementing Classes:

AbstractListenerWebSocketSession, AbstractWebSocketSession, JettyWebSocketSession, NettyWebSocketSessionSupport, ReactorNettyWebSocketSession, StandardWebSocketSession, TomcatWebSocketSession, UndertowWebSocketSession
```
public interface WebSocketSession
```
Represents a WebSocket session.
Use session.receive() to compose on the inbound message stream, and session.send(publisher) to provide the outbound message stream.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method and Description
`WebSocketMessage`	`binaryMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)` Factory method to create a binary WebSocketMessage using the `bufferFactory()` for the session.
`DataBufferFactory`	`bufferFactory()` Return a `DataBuffer` Factory to create message payloads.
`default reactor.core.publisher.Mono<Void>`	`close()` Close the WebSocket session with `CloseStatus.NORMAL`.
`reactor.core.publisher.Mono<Void>`	`close(CloseStatus status)` Close the WebSocket session with the given status.
`reactor.core.publisher.Mono<CloseStatus>`	`closeStatus()` Provides access to the `CloseStatus` with which the session is closed either locally or remotely, or completes empty if the session ended without a status.
`Map<String,Object>`	`getAttributes()` Return the map with attributes associated with the WebSocket session.
`HandshakeInfo`	`getHandshakeInfo()` Return information from the handshake request.
`String`	`getId()` Return the id for the session.
`boolean`	`isOpen()` Whether the underlying connection is open.
`WebSocketMessage`	`pingMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)` Factory method to create a ping WebSocketMessage using the `bufferFactory()` for the session.
`WebSocketMessage`	`pongMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)` Factory method to create a pong WebSocketMessage using the `bufferFactory()` for the session.
`reactor.core.publisher.Flux<WebSocketMessage>`	`receive()` Provides access to the stream of inbound messages.
`reactor.core.publisher.Mono<Void>`	`send(org.reactivestreams.Publisher<WebSocketMessage> messages)` Give a source of outgoing messages, write the messages and return a `Mono<Void>` that completes when the source completes and writing is done.
`WebSocketMessage`	`textMessage(String payload)` Factory method to create a text `WebSocketMessage` using the `bufferFactory()` for the session.

  - getId
```
String getId()
```
    Return the id for the session.
  - getHandshakeInfo
```
HandshakeInfo getHandshakeInfo()
```
    Return information from the handshake request.
  - bufferFactory
```
DataBufferFactory bufferFactory()
```
    Return a DataBuffer Factory to create message payloads.
    
    Returns:
    
    the buffer factory for the session
  - getAttributes
```
Map<String,Object> getAttributes()
```
    Return the map with attributes associated with the WebSocket session.
    
    Returns:
    
    a Map with the session attributes (never null)

  - receive
```
reactor.core.publisher.Flux<WebSocketMessage> receive()
```
    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.
  - send
```
reactor.core.publisher.Mono<Void> send(org.reactivestreams.Publisher<WebSocketMessage> messages)
```
    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.
  - isOpen
```
boolean isOpen()
```
    Whether the underlying connection is open.
    
    Since:
    
    5.3.1
  - close
```
default reactor.core.publisher.Mono<Void> close()
```
    Close the WebSocket session with CloseStatus.NORMAL.
  - close
```
reactor.core.publisher.Mono<Void> close(CloseStatus status)
```
    Close the WebSocket session with the given status.
    
    Parameters:
    
    status - the close status
  - closeStatus
```
reactor.core.publisher.Mono<CloseStatus> closeStatus()
```
    Provides access to the CloseStatus with which the session is closed either locally or remotely, or completes empty if the session ended without a status.
    
    Since:
    
    5.3
  - textMessage
```
WebSocketMessage textMessage(String payload)
```
    Factory method to create a text WebSocketMessage using the bufferFactory() for the session.
  - binaryMessage
```
WebSocketMessage binaryMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)
```
    Factory method to create a binary WebSocketMessage using the bufferFactory() for the session.
  - pingMessage
```
WebSocketMessage pingMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)
```
    Factory method to create a ping WebSocketMessage using the bufferFactory() for the session.
  - pongMessage
```
WebSocketMessage pongMessage(Function<DataBufferFactory,DataBuffer> payloadFactory)
```
    Factory method to create a pong WebSocketMessage using the bufferFactory() for the session.
