Detailed Description

Creator/merger of AliMUONContour objects.

Definition at line 27 of file AliMUONContourMaker.h.

Constructor & Destructor Documentation

AliMUONContourMaker::AliMUONContourMaker ( )

Maker/merger of contours. Can create contour from a set polygons or merger a set of contours into a single one.

This is based on (one of the) algorithm found in Diane L. Souvaine and Iliana Bjorling-Sachs, Proceedings of the IEEE, Vol. 80, No. 9, September 1992, p. 1449

Note that besides the AliMUON prefix, nothing is really MUON specific in this class...

AliMUONContour * AliMUONContourMaker::CreateContour ( const TObjArray &  polygons,
const char *  name = 0x0 
) const

Create the contour of the polygon array and get back the intermediate verticals and horizontal segments both arrays are arrays of AliMUONSegment objects.

AliMUONContour * AliMUONContourMaker::FinalizeContour ( const TObjArray &  verticals,
const TObjArray &  horizontals 
) const
private

For a list of vertical and horizontal edges, we build the final contour object.

void AliMUONContourMaker::GetVerticalEdges ( const TObjArray &  polygons,
TObjArray &  polygonVerticalEdges 
) const
private

From an array of polygons, extract the list of vertical edges. Output array polygonVerticalEdges should be empty before calling.

TArrayD &  yPositions

Merge all the polygons of all contours into a single contour

void AliMUONContourMaker::SortPoints ( const TObjArray &  polygonVerticalEdges,
TObjArray &  sortedPoints 
) const

Sort the point of the vertical edges in ascending order, first on ordinate, then on abcissa, and put them in output vector sortedPoints. Output array sortedPoints should be empty before calling this method.
