Detailed Description

Manages "current" screen by channelling data and keypresses to a FMC Handler.

Member Function Documentation

connectToServer()

void FMCManager::connectToServer	(	std::string	host,
		int	port
	)

connect to the server

Well not really a "connection" since we use the UDP interface, but this at least creates the XPlaneUDPClient instance. It's actually possible to connect to a server that isn't there, so ...

We track the "current" connection server by name, so if it if the connection is for a different server, the the old connection is shutdown first.

onExtPlaneConnect()

void FMCManager::onExtPlaneConnect

(

)

called when server connected.

We should subscribe to datarefs we need here.

receiveDataFromServer()

void FMCManager::receiveDataFromServer	(	std::string	type,
		std::string	dataref,
		std::string	value
	)

callback from network client

This is called whenever a dataref update is received from the client.

setCurrentFMC()

void FMCManager::setCurrentFMC

(

std::string

fmc

)

sets current FMC based on string

Used to set an active FMC, by pressing EXEC in selectFMC. Looks up the instance by name in actualFMCs, then calls setCurrentFMC (AbstractFMC * fmc).

Parameters

fmc

setDataRef()

void FMCManager::setDataRef	(	std::string	dataref,
		std::string	value
	)

set dataref on the server

subscribeDataRef()

void FMCManager::subscribeDataRef	(	std::string	dataref,
		float	accuracy = 0
	)

subscribe to a dataref from the current server

Parameters

dataref

tick()

void FMCManager::tick

(

)

called once every second by Screen's mainloop

unsubscribeDataRef()

void FMCManager::unsubscribeDataRef

(

std::string

dataref

)

unsubscribe from a dataref from the current server

Parameters

dataref

Member Data Documentation

clearKeyPressTime

time_t FMCManager::clearKeyPressTime = 0

protected

track time when CLR was pressed.

Used to trigger going to Select screen if held for more than 2 seconds.

currentConnection

std::string FMCManager::currentConnection

protected

tracker for current server we're connected to.

a contraction of host + ":" + port. We just use this to see if a connection request is to a different server, in which case we shutdown the old connection first.

xplaneConnection

XPlaneExtPlaneClient::ExtPlaneClient* FMCManager::xplaneConnection

protected

our "connection" to the server
