/*
|
|
* This is a simple class to handle special input devices. Update()
|
|
* will be called during the input update; the derived class should
|
|
* send appropriate events to InputHandler.
|
|
*
|
|
* Note that, if the underlying device is capable of it, you're free to
|
|
* start a blocking thread; just store inputs in your class and send them
|
|
* off in a batch on the next Update. Later on, this method will let us
|
|
* get much more accurate timestamps, especially if we have access to realtime
|
|
* threading: we can get events more quickly and timestamp them, instead of
|
|
* having a rough timing granularity due to the framerate. We can't do this
|
|
* with SDL, though.
|
|
*
|
|
* Send input events for a specific type of device. Only one driver
|
|
* for a given set of InputDevice types should be loaded for a given
|
|
* arch. For example, any number of drivers may produce DEVICE_PUMPn
|
|
* events, but only one may be loaded at a time. (This will be inconvenient
|
|
* if, for example, we have two completely distinct methods of getting
|
|
* input for the same device; we have no method to allocate device numbers.
|
|
* We don't need this now; I'll write it if it becomes needed.)
