The AMFChannel relies on network services native to Flash Player and AIR, and exposed to ActionScript by the NetConnection class. This channel uses NetConnection exclusively, and creates a new NetConnection per instance.
Channels are created within the framework using the
ServerConfig.getChannel()
method. Channels can be constructed
directly and assigned to a ChannelSet if desired.
Channels represent a physical connection to a remote endpoint. Channels are shared across destinations by default. This means that a client targetting different destinations may use the same Channel to communicate with these destinations.
When used in polling mode, this Channel polls the server for new messages
based on the polling-interval-seconds
property in the configuration file,
and this can be changed by setting the pollingInterval
property.
The default value is 3 seconds.
To enable polling, the channel must be connected and the polling-enabled
property in the configuration file must be set to true
, or the
pollingEnabled
property of the Channel must be set to true
.
