 Abstract base class for handling system events.                      
                                                                      


TFileHandler(int fd, int mask)
 Create a file descriptor event handler.

Bool_t Notify()
 Notify when event occured on descriptor associated with this handler.

Bool_t ReadNotify()
 Notify when something can be read from the descriptor associated with
 this handler.

Bool_t WriteNotify()
 Notify when something can be written to the descriptor associated with
 this handler.

Bool_t HasReadInterest()
 True if handler is interested in read events.

Bool_t HasWriteInterest()
 True if handler is interested in write events.

void Add()
 Add file event handler to system file handler list.

void Remove()
 Remove file event handler from system file handler list.
