Detailed Description

template<CellWithLabel cell_t, EConnectionType connection_type = EConnectionType::CommonEdgeOrCorner>
struct Acts::InPlaceClusterization::ConnectionHelper< cell_t, connection_type >

default connection helper which should work for arbitrary cells which fulfil the CellWithLabelConcept

The connection helper provides variants to test for common edges and corners or edges only and whether the search for connections can be aborted given the absolute differences of the coordinates of a pair of cells. The tests are static and the helper does not have any data members. There should not be any overhead.

test whether the search for connections can be aborted.

the search is performed in descending order in one coordinate, once the difference in this coordinate is too large the search can be aborted because there cannot be any further connections.
