Public Member Functions

void run ()
 run is inherited by each Handler class. It is called from the main while loop in main.cpp. It runs through the state machine, specific to each Handler class.
void setRequest (int request, void *data=0)
 setRequest sets a request that the handler will complete when it is able to

Protected Attributes

MyTimers * m_timer
