Constructor	Description
WebsocketPushContext(String channel, WebsocketSessionManager socketSessions, WebsocketUserManager socketUsers)	Creates a socket push context whereby the mutable map of session and view scope channel identifiers is referenced, so it's still available when another thread invokes send(Object) during which the session and view scope is not necessarily active anymore.

Method Summary

Modifier and Type	Method	Description
Set<Future<Void>>	send(Object message)	Send given message object to the push socket channel as identified by @Push.
<S extends Serializable> Map<S,Set<Future<Void>>>	send(Object message, Collection<S> users)	Send given message object to the push socket channel as identified by @Push, targeted to the given users as identified by <f:websocket user>.
<S extends Serializable> Set<Future<Void>>	send(Object message, S user)	Send given message object to the push socket channel as identified by @Push, targeted to the given user as identified by <f:websocket user>.

WebsocketPushContext

public WebsocketPushContext(String channel, WebsocketSessionManager socketSessions, WebsocketUserManager socketUsers)

Creates a socket push context whereby the mutable map of session and view scope channel identifiers is referenced, so it's still available when another thread invokes send(Object) during which the session and view scope is not necessarily active anymore.

Method Details

send

public Set<Future<Void>> send(Object message)

Description copied from interface: PushContext

Send given message object to the push socket channel as identified by @Push. The message object will be encoded as JSON and be available as first argument of the JavaScript listener function declared in <f:websocket onmessage>.

Specified by:

send in interface PushContext

Parameters:

message - The push message object.

Returns:

The results of the send operation. If it returns an empty set, then there was no open web socket session associated with given socket channel. The returned futures will return null on Future.get() if the message was successfully delivered and otherwise throw ExecutionException.

send

public <S extends Serializable> Set<Future<Void>> send(Object message, S user)

Description copied from interface: PushContext

Send given message object to the push socket channel as identified by @Push, targeted to the given user as identified by <f:websocket user>. The message object will be encoded as JSON and be available as first argument of the JavaScript listener function declared in <f:websocket onmessage>.

Specified by:

send in interface PushContext

Type Parameters:

S - The generic type of the user identifier.

Parameters:

message - The push message object.

user - The user to which the push message object must be delivered to.

Returns:

The results of the send operation. If it returns an empty set, then there was no open web socket session associated with given socket channel and user. The returned futures will return null on Future.get() if the message was successfully delivered and otherwise throw ExecutionException.

send

public <S extends Serializable> Map<S,Set<Future<Void>>> send(Object message, Collection<S> users)

Description copied from interface: PushContext

Send given message object to the push socket channel as identified by @Push, targeted to the given users as identified by <f:websocket user>. The message object will be encoded as JSON and be available as first argument of the JavaScript listener function declared in <f:websocket onmessage>.

Specified by:

send in interface PushContext

Type Parameters:

S - The generic type of the user identifier.

Parameters:

message - The push message object.

users - The users to which the push message object must be delivered to.

Returns:

The results of the send operation grouped by user. If it contains an empty set, then there was no open web socket session associated with given socket channel and user. The returned futures will return null on Future.get() if the message was successfully delivered and otherwise throw ExecutionException.
