Member Function Documentation

void ER::Main ( ) [virtual]

Main method for driver thread.

drivers have their own thread of execution, created using StartThread(); this is the entry point for the driver thread, and must be overloaded by all threaded drivers.

Implements ThreadedDriver.

void ER::MainQuit ( void  ) [virtual]

Cleanup method for driver thread (called when main exits)

Overload this method and to do additional cleanup when the driver thread exits.

Reimplemented from ThreadedDriver.
