AbstractServerTransport.Scheduler (CometD :: Java 6.0.19 API)

All Known Subinterfaces:

AbstractHttpTransport.HttpScheduler

All Known Implementing Classes:

AbstractHttpTransport.LongPollScheduler, AbstractServerTransport.Scheduler.None, AbstractStreamHttpTransport.DispatchingLongPollScheduler

Enclosing class:

AbstractServerTransport
```
public static interface AbstractServerTransport.Scheduler
```
Performs server-to-client transport operations when a /meta/connect message is held and a server-side message is published.

HTTP transports can only perform server-to-client sends if there is an outstanding /meta/connect, or if they are processing incoming messages.

WebSocket transports, on the other hand, can perform server-to-client sends even if there is no outstanding /meta/connect.

Method Summary

All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default void`	`cancel()`	Invoked when the transport wants to cancel scheduled operations that will trigger when the /meta/connect timeout fires.
`default void`	`cancel(java.lang.Throwable cause)`	Invoked when the transport wants to cancel with the given cause scheduled operations that will trigger when the /meta/connect timeout fires.
`default void`	`destroy()`	Invoked when the transport wants to abort communication.
`default ServerMessage.Mutable`	`getMessage()`
`default long`	`getMetaConnectCycle()`
`default void`	`schedule()`	Invoked when the transport wants to send queued messages, and possibly a /meta/connect reply.
