Examples of flex.messaging.client.FlexClient$EndpointQueue

flex.messaging.client.FlexClient
@exclude Helper class that stores per-endpoint outbound queue state including:
- flexClient - The FlexClient the queue is used by.
- messages - The outbound queue of messages for the endpoint.
- processor - The processor that handles adding messages to the queue as well as flushing them to the network.
- asyncPoll - The async poll to timeout or callback when messages arrive (null if the endpoint or session supports direct push).
- pushSession - A reference to a pushSession to use for direct writes to the client (null if the endpoint uses polling or handles push directly).
- flushTask - A reference to a pending flush task that will perform a delayed flush of the queue; null if no delayed flush has been scheduled.
- messageClientRefCount - A reference count of MessageClients subcribed over this endpoint. Once all MessageClients unsubscribe this queue can be shut down.
- avoidBusyPolling - Used to signal poll result generation for the queue to avoid busy polling.
