NetMonitor

Package	flash.net
Class	public class NetMonitor
Inheritance	NetMonitor EventDispatcher Object

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10.3, AIR 2.7

The NetMonitor class maintains a list of NetStream objects.

Use the NetMonitor class to keep track of NetStream objects in use in an application. An instance of this class dispatches a netStreamCreate event whenever a new NetStream object is created.

You can use the NetMonitor class to help track video playback and related events without regard to the specific video player being used. This facility can be helpful when implementing media measurement, analytics, and usage tracking libraries.

Note: NetStream monitoring is not supported by Flash Player in the browser on Android and Blackberry Tablet OS, or by AIR on iOS.

()

method

public function listStreams():Vector.<NetStream>

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10.3, AIR 2.7

Retrieves all NetStream objects belonging to this NetMonitor object's security context.

Avoid caching the list of NetStream objects. Maintaining a reference to these NetStream objects can introduce memory leaks into an application by preventing the garbage collector from reclaiming an object's resources when it is no longer being used.

Note: if the NetStream monitoring is not supported on the current platform, the list returned by this function is always empty.

Returns

Vector.<NetStream> — Vector of NetStream objects

Event

Event Object Type: flash.events.NetMonitorEvent
property NetMonitorEvent.type = flash.events.NetMonitorEvent.NET_STREAM_CREATE

Language Version:

ActionScript 3.0

Runtime Versions:

Flash Player 10.3, AIR 2.7

Dispatched when a new NetStream object is created within the security context of this NetMonitor instance.

Note: if the NetStream monitoring is not supported on the current platform, netStreamCreate events are not dispatched.

The NetMonitorEvent.NET_STREAM_CREATE constant defines the value of the type property of an netStreamCreate event object.

The netStreamCreate event has the following properties:

Property	Value
`netStream`	NetStream object that has been created.
`bubbles`	`false`
`cancelable`	`false`; there is no default behavior to cancel.
`currentTarget`	The object that is actively processing the Event object with an event listener.
`target`	The object beginning or ending a session.
