| IMergedFeedListener Interface |
A listener that merges together messages picked up by two or more listeners.
Namespace: VirtualRadar.Interface.Listener
Assembly: VirtualRadar.Interface (in VirtualRadar.Interface.dll) Version: 1.0.0.0 (1.0.0.0)
SyntaxThe IMergedFeedListener type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | BytesExtractor |
Gets the object that can extract the important bytes from the stream. Do not modify any properties on the extractor directly,
always use ChangeSource(IConnector, IMessageBytesExtractor, IRawMessageTranslator) to perform configuration changes.
(Inherited from IListener.) |
| ConnectionStatus |
Gets a value indicating whether the listener is connected to the source of aircraft message data.
(Inherited from IListener.) |
| Connector |
Gets the connector that is handling the connection for the listener. Do not modify any properties on the connection directly,
always use ChangeSource(IConnector, IMessageBytesExtractor, IRawMessageTranslator) to perform configuration changes.
(Inherited from IListener.) |
| IcaoTimeout |
Gets or sets the number of milliseconds that must elapse after the last message from a given ICAO on a receiver before
that receiver is no longer considered to be the only source of messages for that ICAO.
|
| IgnoreAircraftWithNoPosition |
Gets or sets a value indicating whether messages from aircraft are ignored until they transmit a position.
|
| IgnoreBadMessages |
Gets or sets a value indicating whether exceptions thrown by the message translator cause a disconnection
and raise ExceptionCaught or whether they are ignored.
(Inherited from IListener.) |
| IsSatcomFeed |
Gets or sets a value indicating that this is a satcom feed.
(Inherited from IListener.) |
| Listeners |
Gets the list of listeners that will be merged into a single feed.
|
| RawMessageTranslator |
Gets the object that translates raw messages into Port30003 format messages. Do not modify any properties on the translator directly,
always use ChangeSource(IConnector, IMessageBytesExtractor, IRawMessageTranslator) to perform configuration changes.
(Inherited from IListener.) |
| ReceiverId |
Gets or sets the identity of the receiver that is controlling this listener.
(Inherited from IListener.) |
| ReceiverName |
Gets or sets the name of the receiver that is controlling this listener.
(Inherited from IListener.) |
| Statistics |
Gets the statistics for the listener.
(Inherited from IListener.) |
| TotalBadMessages |
Gets a count of the total number of messages that could not be translated.
(Inherited from IListener.) |
| TotalMessages |
Gets a count of the total number of messages received by the object.
(Inherited from IListener.) |
Methods| Name | Description | |
|---|---|---|
 | ChangeSource |
Changes the connector and/or message bytes extractor used by the listener.
(Inherited from IListener.) |
| Connect |
Connects to the source of aircraft data. Incoming messages from the source will raise events on the listener.
(Inherited from IListener.) |
| Disconnect |
Called implicitly by Dispose, disconnects from the source of aircraft message data.
(Inherited from IListener.) |
| Dispose | Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Inherited from IDisposable.) |
| SetListeners |
Sets the Listeners list.
|
Events| Name | Description | |
|---|---|---|
 | ConnectionStateChanged |
Raised when the listener connects or disconnects. Note that exceptions raised during parsing of
messages will cause the object to automatically disconnect.
(Inherited from IListener.) |
| ExceptionCaught |
Raised when an exception is caught on the background thread. The background thread should not
pass ThreadAbortException through this.
(Inherited from IBackgroundThreadExceptionCatcher.) |
| ModeSBytesReceived |
Raised when bytes representing a Mode-S message have been received. This may not be on the same thread that started
the listener - however all messages are guaranteed to be transmitted in the order in which they were received.
(Inherited from IListener.) |
| ModeSMessageReceived |
Raised when a message has been received from the source of raw data. This may not be on the same thread that
started the listener - however all messages are guaranteed to be transmitted in the order in which they
were received.
(Inherited from IListener.) |
| Port30003MessageReceived |
Raised when a message has been received from a source of Port30003 data. This may not be on the same thread
that started the listener - however all messages are guaranteed to be transmitted in the order in which they
were received.
(Inherited from IListener.) |
| PositionReset |
Raised when a decoder that the listener is using to translate messages indicates that the previous position
reported for an aircraft was wrong and that its position has been reset.
(Inherited from IListener.) |
| RawBytesReceived |
Raised when bytes have been received from the data source. This may not be on the same thread that started
the listener - however all messages are guaranteed to be transmitted in the order in which they were received.
(Inherited from IListener.) |
| SourceChanged |
Raised when the listener is asked to change source of data. If the change in source causes a disconnect and
reconnect then this event is raised after the disconnect but before the reconnect.
(Inherited from IListener.) |
RemarksCalls on the merged feed's version of methods like Connect etc. have no effect on the receivers that the feed is merging together - all the merged feed is doing is taking the messages from the receivers and merging them together. Many properties, events and methods on IListener are stubs on the merged feed. The only properties, events and methods that are fully operational are:
TotalMessagesTotalBadMessagesExceptionCaughtPort30003MessageReceivedPositionResetSpecifically, the connection is always on and cannot be turned off. To control the receivers that the feed is merging you must send messages to each receiver.
