makVre::DtRwrMonitor Class Reference

Detailed Description

DtRwrMonitor manages the communication of radar warning receiver contact information between an RWR system and visualization systems. It handles subscription requests from clients, maintains a list of current subscribers, and sends RWR data messages when the contact list changes.

DtSubscriberListCounter

using makVre::DtRwrMonitor::DtSubscriberListCounter = std::map<DtSimulationAddress, int>

protected

Type definition for the subscriber list with counter.

Defines the container type used to store simulation addresses of subscribers with a counter for each to track multiple subscriptions from the same client.

Constructor & Destructor Documentation

DtRwrMonitor() [1/3]

makVre::DtRwrMonitor::DtRwrMonitor ( )

private

Default constructor (not implemented)

Default constructor is private and not implemented to prevent creation of instances without proper initialization.

Referenced by DtRwrMonitor(), and operator=().

DtRwrMonitor() [2/3]

makVre::DtRwrMonitor::DtRwrMonitor ( const DtRwrMonitor & orig )

private

Copy constructor (not implemented)

Copy constructor is private and not implemented to prevent copy construction.

References DtRwrMonitor().

DtRwrMonitor() [3/3]

makVre::DtRwrMonitor::DtRwrMonitor	(	DtLocalObject *	hostObject,
		const DtRwrContactInfoList *	contactInfoList )

Constructor.

Parameters

hostObject	The local object that owns the RWR this monitor is for
contactInfoList	Pointer to the RWR contact information list maintained by the RWR

Creates a new RWR monitor that will handle communication between the specified RWR system and visualization clients.

~DtRwrMonitor()

virtual makVre::DtRwrMonitor::~DtRwrMonitor ( )

virtual

Virtual destructor.

Cleans up resources used by the RWR monitor.

Member Function Documentation

operator=()

const DtRwrMonitor & makVre::DtRwrMonitor::operator= ( const DtRwrMonitor & orig )

private

Assignment operator (not implemented)

Returns

Reference to this object

Assignment operator is private and not implemented to prevent assignment.

References DtRwrMonitor().

init()

virtual bool makVre::DtRwrMonitor::init ( )

virtual

Initializes the monitor.

Returns

True if initialization is successful, false otherwise

Initializes the monitor by registering message callbacks to handle subscription requests from clients. Called after construction.

registerMessageCallbacks()

virtual void makVre::DtRwrMonitor::registerMessageCallbacks ( )

virtual

Registers message callbacks for RWR data requests.

Registers callback functions to handle rwrDataRequest and rwrDataUnsubscribe messages from visualization clients.

rwrDataRequestCallback()

static void makVre::DtRwrMonitor::rwrDataRequestCallback ( DtSimMessage * msg, void * usrData )

static

Static callback function for RWR data request messages.

Parameters

msg	The simulation message containing the request
usrData	User data pointer (contains the monitor instance)

Static function registered as a callback to handle RWR data request messages. Forwards the request to the appropriate monitor instance.

processRwrDataRequest()

virtual void makVre::DtRwrMonitor::processRwrDataRequest ( DtSimMessage * msg )

virtual

Processes an RWR data request message.

Parameters

msg	The simulation message containing the request

Handles subscription requests for RWR data, adding the client to the subscriber list and sending initial data.

rwrDataUnsubscribeCallback()

static void makVre::DtRwrMonitor::rwrDataUnsubscribeCallback ( DtSimMessage * msg, void * usrData )

static

Static callback function for RWR data unsubscribe messages.

Parameters

msg	The simulation message containing the unsubscribe request
usrData	User data pointer (contains the monitor instance)

Static function registered as a callback to handle RWR data unsubscribe messages. Forwards the request to the appropriate monitor instance.

processRwrDataUnsubscribe()

virtual void makVre::DtRwrMonitor::processRwrDataUnsubscribe ( DtSimMessage * msg )

virtual

Processes an RWR data unsubscribe message.

Parameters

msg	The simulation message containing the unsubscribe request

Handles unsubscription requests for RWR data, removing the client from the subscriber list.

createAndSendRwrDataMessage()

virtual void makVre::DtRwrMonitor::createAndSendRwrDataMessage ( )

virtual

Creates and sends an RWR data message to subscribers.

Constructs a DtRwrData message based on the current state of the RWR contact list and sends it to all current subscribers. This provides visualization clients with up-to-date RWR contact information.

notifyTargetsChanged()

virtual void makVre::DtRwrMonitor::notifyTargetsChanged ( )

virtual

Notifies that the RWR contact list has changed.

Called by the RWR system whenever its contact list changes. This triggers RWR data messages to be sent out to all current subscribers, ensuring they have the latest contact information.

addToSubscriberList()

virtual void makVre::DtRwrMonitor::addToSubscriberList ( const DtSimulationAddress & add )

protectedvirtual

Adds a client to the subscriber list.

Parameters

add	The simulation address of the client to add

Adds the specified client address to the list of subscribers for this RWR's data. Maintains a counter for each address to support multiple subscriptions from the same client.

removeFromSubscriberList()

virtual void makVre::DtRwrMonitor::removeFromSubscriberList ( const DtSimulationAddress & add )

protectedvirtual

Removes a client from the subscriber list.

Parameters

add	The simulation address of the client to remove

Removes one subscription entry for the specified client address from the list of subscribers. Only completely removes the client when all subscription instances are removed.

numberOfSubscribers()

virtual int makVre::DtRwrMonitor::numberOfSubscribers ( )

protectedvirtual

Gets the number of current subscribers.

Returns

The number of clients currently subscribed to this RWR's data

Returns the count of unique clients currently subscribed to receive RWR data updates.
