Detailed Description

This classe builds the Cellular Automaton from the hits.

It can be used to take all the autHits stored in a map< int , vector < IHits > > and makes 1-hit-segments out of them ( see the class Segment for more info on them ).

The created 1-segments then are connected.

For the rules of connecting criteria and hitConnectors can be added to the object:

• a hitConnector takes the sector of the segment ( for example a cellID0 or a layer number or an own code ) and returns all the sectors we might connect to. So there we get the information like: "this segment can be connected to layer 3 and 4, module 7,8,9 in forward direction".
• the criteria take two segments and return whether they are compatible or not. A criterion could check for anything, that is stored in the segments. For example: if the line formed from two 1-hit segments passes close by the IP might be a criterion for very stiff tracks.

So the hitConnectors tell us were to look and the criteria whether to connect. If two 1-hit segments are found, that are compatible, they will be connected. Connected means: The inner 1-segment will save the outer one as a parent and the outer one will save the inner one as a child.

All this (except adding hitConnectors and Criteria) is done in the method get1SegAutomaton.

This method finally then returns an automaton (segments sorted by their layers), ready to be used.

Returns

An automaton containing all the hits from the FTDRepresentation sorted now by layers. (attention: those are not necessarily the same layers as the FTD layers). Also they are connected.
