info | property |
info:Object
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9, Flash Lite 4 |
An object with properties that describe the object's status or error condition.
The information object could have a code
property containing a string
that represents a specific event or a level
property containing a string
that is either "status"
or "error"
.
The information object could also be something different. The code
and
level
properties might not work for some implementations and some servers
might send different objects.
P2P connections send messages to a NetConnection
with a stream
parameter
in the information object that indicates which NetStream
the message pertains to.
For example, Flex Data Services sends Message
objects that cause coercion errors if you try to access the code
or
level
property.
The following table describes the possible string values of the code
and level
properties.

The info.from:String property is the groupAddress from which the message was received. The info.fromLocal:Boolean property is TRUE if the message was sent by this node (meaning the local node is the nearest to the destination group address), and FALSE if the message was received from a different node.

"NetStream.Play.Transition" | "status" | (Flash Media Server 3.5) The server received the command to transition to another stream as a result of bitrate stream switching. This code indicates a success status event for the NetStream.play2() call to initiate a stream switch. If the switch does not succeed, the server sends a NetStream.Play.Failed event instead.
When the stream switch occurs, an onPlayStatus event with a code of "NetStream.Play.TransitionComplete" is dispatched. For Flash Player 10 and later. |
"NetStream.Play.UnpublishNotify" | "status" | An unpublish from a stream is sent to all subscribers. |
"NetStream.Publish.BadName" | "error" | Attempt to publish a stream which is already being published by someone else. |

past the end of the video data that has downloaded thus far, or past
the end of the video once the entire file has downloaded. The info.details property of the event object contains a time code

Example ( How to use this example )
"NetStream.Seek.InvalidTime"
error.
The "NetStream.Seek.InvalidTime"
error
happens when the user attempts to seek beyond the end of the downloaded stream. The example
tests the value of the event object's info.code
property. In case the error occurs,
the eventObj.info.details
property is assigned to a variable
to use as a parameter for the stream's seek()
method. The eventObj.info.details
contains the last valid position available to handle the error. So, the user goes to a valid location
at the end of the downloaded stream.
function videoStatus(eventObj:NetStatusEvent):Void { switch(eventObj.info.code) { case "NetStream.Seek.InvalidTime": { var validSeekTime:Number = eventObj.info.details; nStream.seek(validSeekTime); break; } } }
NetStatusEvent | () | Constructor |
public function NetStatusEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, info:Object = null)
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9, Flash Lite 4 |
Creates an Event object that contains information about netStatus
events.
Event objects are passed as parameters to event listeners.
type:String — The type of the event. Event listeners can access this information through the inherited type property. There is only one type of status event: NetStatusEvent.NET_STATUS .
| |
bubbles:Boolean (default = false ) — Determines whether the Event object participates in the bubbling stage of the event flow. Event listeners can access this information through the inherited bubbles property.
| |
cancelable:Boolean (default = false ) — Determines whether the Event object can be canceled. Event listeners can access this information through the inherited cancelable property.
| |
info:Object (default = null ) — An object containing properties that describe the object's status. Event listeners can access this object through the info property.

clone | () | method |
override public function clone():Event
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9, Flash Lite 4 |
Creates a copy of the NetStatusEvent object and sets the value of each property to match that of the original.
ReturnsEvent — A new NetStatusEvent object with property values that match those of the original.
|
toString | () | method |
override public function toString():String
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9, Flash Lite 4 |
Returns a string that contains all the properties of the NetStatusEvent object. The string is in the following format:
[NetStatusEvent type=value bubbles=value cancelable=value info=value]
String — A string that contains all the properties of the NetStatusEvent object.
|
NET_STATUS | Constant |
public static const NET_STATUS:String = "netStatus"
Language Version: | ActionScript 3.0 |
Runtime Versions: | AIR 1.0 Flash Player 9, Flash Lite 4 |
Defines the value of the type
property of a netStatus
event object.
This event has the following properties:
Property | Value |
---|---|
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. |
info | An object with properties that describe the object's status or error condition. |
target | The NetConnection or NetStream object reporting its status. |
See also
In this example, the netStatusHandler
method is registered as a listener for
the NetStatusEvent event NetConnection.netStatus
.
When the status (success or failure) of the NetConnection.connect()
attempt
is determined, the netStatus
event triggers this method. If the
attempt to connect to the NetConnection object is successful (in other words,
if the info
property of the NetStatusEvent object dispatched by the netStatus
event has a code
property that indicates success), the code creates the Video and NetStream
objects and calls the Video.attachNetStream()
and NetStream.play()
methods.
Note: To run this example, you need an FLV file
whose name and location match the variable passed to videoURL
;
in this case, an FLV file called Video.flv that is in the same directory as the SWF file.
