- (void) invoke:

(NSInvocation *)

invocation

invoke a method in the timing thread

- (void) performSelector:		(SEL)	aSelector
onObject:		(id)	anObject

Perform a selector on a given object in the timing thread.

- (void) performSelector:		(SEL)	aSelector
onObject:		(id)	theObject
withParams:		(void *)	firstParam
,			...

Perform a selector on a given object in the timing thread.

Allows you to pass a variable number of parms, the param list must be NULL terminated, and must have the smae number of params as the selector expects

- (void) performSelector:		(SEL)	aSelector
withObject:		(id)	anObject
withObject:		(id)	anotherObject
onObject:		(id)	theObject

Perform a selector on a given object in the timing thread.

Allows you to pass two parameters

+ (LOTimingThread *) sharedTimingThread

Get the default thread for the application.

- (void) stopThread

Stop the timing thread.

- (BOOL) tap

Accept a users tap.

Returns:

YES if enough taps have been done to create a meaningful tap interval

- (unsigned) tapBPM
