public function NetStreamSwitchManager(connection:NetConnection, netStream:NetStream, resource:DynamicStreamingResource, metrics:NetStreamMetricsBase, switchingRules:Vector.<SwitchingRuleBase>, autoSwitch:Boolean = true)| 語言版本: | ActionScript 3.0 |
| 產品版本: | OSMF 1.0 |
| 執行階段版本: | Flash Player 10, AIR 1.5 |
Constructor.
參數connection:NetConnection — The NetConnection for the NetStream that will be managed.
| |
netStream:NetStream — The NetStream to manage.
| |
resource:DynamicStreamingResource — The DynamicStreamingResource that is playing in the NetStream.
| |
metrics:NetStreamMetricsBase — The provider of runtime metrics.
| |
switchingRules:Vector.<SwitchingRuleBase> — The switching rules that this manager will use.
| |
autoSwitch:Boolean (default = true) |
canAutoSwitchNow | () | 方法 |
protected function canAutoSwitchNow(newIndex:int):BooleanOverride this method to provide additional decisioning around allowing automatic switches to occur. This method will be invoked just prior to a switch request. If false is returned, that switch request will not take place.
By default, the implementation does the following:
1) When a switch down occurs, the stream being switched from has its failed count incremented. If, when the switching rules are evaluated again, a rule suggests switching up, since the stream previously failed, it won't be tried again until a duration (30s) elapses. This provides a better user experience by preventing a situation where the switch up is attempted but then fails almost immediately.
2) Once a stream item has 3 failures, there will be no more attempts to switch to it until an interval (5m) has expired. At the end of this interval, all failed counts are reset to zero.
參數
newIndex:int — The new index to switch to.
