Descrizione delle proprietà

reliableReconnectDuration

proprietà

public var reliableReconnectDuration:int

The duration in milliseconds that channels within the AdvancedChannelSet will attempt to reconnect in a reliable fashion to the remote endpoint they where previous connected to, before advancing to the normal automatic failover and protocol fallback algorithm. The default value, 0, triggers a single reliable reconnect attempt. Assigned values must be 0 or greater and for any value larger than 0, in the event of a network disconnect, attempts will be made to re-establish the pre-existing reliable connection for the specified time duration in milliseconds.

Genera

RangeError — If a negative value is assigned.

()

Funzione di costruzione

public function AdvancedChannelSet(channelIds:Array = null, clusteredWithURLLoadBalancing:Boolean = false)

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Adobe Digital Enterprise Platform Data Services per Java EE 3

Versioni runtime:

Flash Player 9, AIR 1.1

Constructs an AdvancedChannelSet. If the channelIds argument is provided, the AdvancedChannelSet will use automatically configured Channels obtained via ServerConfig.getChannel() to reach a destination. Attempting to manually assign Channels to an AdvancedChannelSet that uses configured Channels is not allowed.

If the channelIds argument is not provided or is null, Channels must be manually created and added to the AdvancedChannelSet in order to connect and send messages.

If the AdvancedChannelSet is clustered using url-load-balancing (where each server declares a unique RTMP or HTTP URL and the client fails over from one URL to the next), the first time that a Channel in the ChannelSet successfully connects the AdvancedChannelSet will automatically make a request for all of the endpoints across the cluster for all member Channels and will assign these failover URLs to each respective Channel. This allows Channels in the ChannelSet to failover individually, and when failover options for a specific Channel are exhausted the AdvancedChannelSet will advance to the next Channel in the set to attempt to reconnect.

Regardless of clustering, if a Channel cannot connect or looses connectivity, the AdvancedChannelSet will advance to its next available Channel and attempt to reconnect. This allows the AdvancedChannelSet to hunt through Channels that use different protocols, ports, etc., in search of one that can connect to its endpoint successfully.

Parametri

	`channelIds:Array` (default = `null`) — The ids of configured Channels obtained from ServerConfig for this AdvancedChannelSet to use. If null, Channels must be manually added to the AdvancedChannelSet.

	`clusteredWithURLLoadBalancing:Boolean` (default = `false`) — True if the Channels in the AdvancedChannelSet are clustered using url load balancing.
