Method Detail

getId

java.lang.String getId()

The ID of the session.

Returns:

The ID of the session

getAttributes

MutableConvertibleValues<java.lang.Object> getAttributes()

Returns:

Only the attributes of the session

isOpen

boolean isOpen()

Whether the session is open.

Returns:

True if it is

isWritable

boolean isWritable()

Whether the session is writable. It may not be writable, if the buffer is currently full

Returns:

True if it is

isSecure

boolean isSecure()

Whether the connection is secure.

Returns:

True if it is secure

getOpenSessions

java.util.Set<? extends WebSocketSession> getOpenSessions()

The current open sessions.

Returns:

The open sessions

getRequestURI

java.net.URI getRequestURI()

The request URI this session was opened under.

Returns:

The request URI

getProtocolVersion

java.lang.String getProtocolVersion()

The protocol version of the WebSocket protocol currently being used.

Returns:

The protocol version

send

<T> org.reactivestreams.Publisher<T> send(T message,
                                          MediaType mediaType)

Send the given message to the remote peer. The resulting Publisher does not start sending until subscribed to. If you return it from Micronaut annotated methods such as OnOpen and OnMessage, Micronaut will subscribe to it and send the message without blocking.

Type Parameters:

T - The message type

Parameters:

message - The message

mediaType - The media type of the message. Used to lookup an appropriate codec via the MediaTypeCodecRegistry.

Returns:

A Publisher that either emits an error or emits the message once it has been published successfully.

sendAsync

<T> java.util.concurrent.CompletableFuture<T> sendAsync(T message,
                                                        MediaType mediaType)

Send the given message to the remote peer asynchronously.

Type Parameters:

T - The message type

Parameters:

message - The message

mediaType - The media type of the message. Used to lookup an appropriate codec via the MediaTypeCodecRegistry.

Returns:

A CompletableFuture that tracks the execution. CompletableFuture.get() and related methods will return the message on success, on error throw the underlying Exception.

sendSync

default void sendSync(java.lang.Object message,
                      MediaType mediaType)

Send the given message to the remote peer synchronously.

Parameters:

message - The message

mediaType - The media type of the message. Used to lookup an appropriate codec via the MediaTypeCodecRegistry.

send

default <T> org.reactivestreams.Publisher<T> send(T message)

Send the given message to the remote peer. The resulting Publisher does not start sending until subscribed to. If you return it from Micronaut annotated methods such as OnOpen and OnMessage, Micronaut will subscribe to it and send the message without blocking.

Type Parameters:

T - The message type

Parameters:

message - The message

Returns:

A Publisher that either emits an error or emits the message once it has been published successfully.

sendAsync

default <T> java.util.concurrent.CompletableFuture<T> sendAsync(T message)

Send the given message to the remote peer asynchronously.

Type Parameters:

T - The message type

Parameters:

message - The message

Returns:

A CompletableFuture that tracks the execution. CompletableFuture.get() and related methods will return the message on success, on error throw the underlying Exception.

default void sendSync(java.lang.Object message)

Send the given message to the remote peer synchronously.

Parameters:

message - The message

getSubprotocol

default java.util.Optional<java.lang.String> getSubprotocol()

The subprotocol if one is used.

Returns:

The subprotocol

getRequestParameters

default ConvertibleMultiValues<java.lang.String> getRequestParameters()

The request parameters used to create this session.

Returns:

The request parameters

getUriVariables

default ConvertibleValues<java.lang.Object> getUriVariables()

Any matching URI path variables.

Returns:

The path variables

getUserPrincipal

default java.util.Optional<java.security.Principal> getUserPrincipal()

The user Principal used to create the session.

Returns:

The Principal

close

void close()

Specified by:
