Method Details

extractOfferedWsProtocols

public Route extractOfferedWsProtocols(Function<List<String>,Route> inner)

Extract the list of WebSocket subprotocols as offered by the client in the {@link Sec-WebSocket-Protocol} header if this is a WebSocket request. Rejects with an ExpectedWebSocketRequestRejection, otherwise.

Parameters:

inner - (undocumented)

Returns:

(undocumented)

extractWebSocketUpgrade

public Route extractWebSocketUpgrade(Function<WebSocketUpgrade,Route> inner)

Extract the WebSocketUpgrade attribute if this is a WebSocket request. Rejects with an ExpectedWebSocketRequestRejection, otherwise.

Parameters:

inner - (undocumented)

Returns:

(undocumented)

handleWebSocketMessages

public <T> Route handleWebSocketMessages(org.apache.pekko.stream.javadsl.Flow<Message,Message,T> handler)

Handles WebSocket requests with the given handler and rejects other requests with an ExpectedWebSocketRequestRejection.

Parameters:

handler - (undocumented)

Returns:

(undocumented)

handleWebSocketMessagesForOptionalProtocol

public <T> Route handleWebSocketMessagesForOptionalProtocol(org.apache.pekko.stream.javadsl.Flow<Message,Message,T> handler,
 Optional<String> subprotocol)

Handles WebSocket requests with the given handler and rejects other requests with an ExpectedWebSocketRequestRejection.

If the subprotocol parameter is None any WebSocket request is accepted. If the subprotocol parameter is Some(protocol) a WebSocket request is only accepted if the list of subprotocols supported by the client (as announced in the WebSocket request) contains protocol. If the client did not offer the protocol in question the request is rejected with an UnsupportedWebSocketSubprotocolRejection rejection.

To support several subprotocols you may chain several handleWebSocketMessagesForOptionalProtocol routes.

Parameters:

handler - (undocumented)

subprotocol - (undocumented)

Returns:

(undocumented)

handleWebSocketMessagesForProtocol

public <T> Route handleWebSocketMessagesForProtocol(org.apache.pekko.stream.javadsl.Flow<Message,Message,T> handler,
 String subprotocol)

Handles WebSocket requests with the given handler if the given subprotocol is offered in the request and rejects other requests with an ExpectedWebSocketRequestRejection or an UnsupportedWebSocketSubprotocolRejection.

Parameters:

handler - (undocumented)

subprotocol - (undocumented)

Returns:

(undocumented)
