Implementation of AliMUONVClusterFinder

This class simply find adjacent pads to form clusters

void AliMUONPreClusterFinder::AddPad	(	AliMUONCluster &	cluster,
		AliMUONPad *	pad
	)

private

Add a pad to a cluster

FIXME : we should at that point really find a better way to remove "bad" preclusters, like e.g. computing the charge dispersion (the lower, the most probably we have noise cluster) and/or mean charge per pad (if too close to LowestPadCharge, again that's a noise cluster... BUT this needs carefull testing !

Referenced by NextCluster().

Bool_t AliMUONPreClusterFinder::UsePad ( const AliMUONPad & pad )

virtual

Add a pad to the list of pads to be considered for clustering. Typical usage is to "put-back-in-business" a pad that was part of a previous cluster (returned by NextCluster) but was externally identified of not being part of that cluster, so it must be reuseable. Might not be implemented by all cluster finders... (in which case it must returns kFALSE)
