Detailed Description

Combination of digit and mppad informations.

Object gathering information about a hit pad.

Can be seen as a combination of a Digit (which brings the charge) and an MpPad (which brings location and position)

Also provided are some static functions to compute overlap and get neighboring information.

Bool_t AliMUONPad::AreNeighbours	(	const AliMUONPad &	d1,

	)

static

Whether 2 pads are neighbours or not

Bool_t AliMUONPad::AreOverlapping	(	const AliMUONPad &	d1,
		const AliMUONPad &	d2,
		const TVector2 &	precision,
		AliMpArea &	overlapArea
	)

static

Checks the overlap between 2 pads, and returns the overlap area

See comments on the other AreOverlapping method, too : in this method, the overlapRegion does not depend on the precision parameter, which is only used to decide whether the pads are overlapping, while the actual overlap region is computed w/o reference to precision.

Definition at line 221 of file AliMUONPad.cxx.

Bool_t AliMUONPad::AreOverlapping	(	const AliMUONPad &	d1,
		const AliMUONPad &	d2,
		const TVector2 &	precision
	)

static

Checks the overlap between 2 pads. The actual overlap is computed not on d1 and d2, but on d1 and d2 "re-scaled" using the precision vector (conceptually equivalent to d.Dimensions() += precision)

So, if the elements (x,y) of precision are :

positive, the overlap is "computed" from smaller d1 and d2 which is, modulo the precision, what you would think as a normal overlap calculation
negative, overlap is from "bigger" d1 and d2, which is usefull to "tweek" what we call an overlap, e.g. to consider 2 pads touching only by their corners to be overlapping.
