Detailed Description

Algorithm to build CSCSegment's from CSCRecHit2D collection by implementing a 'build' function required by CSCSegmentProducer.

Implementation notes:
Configured via the Producer's ParameterSet.
Presume this might become an abstract base class one day.

Constructor & Destructor Documentation

CSCSegmentBuilder::CSCSegmentBuilder

(

const edm::ParameterSet &

ps

)

[explicit]

Configure the algorithm via ctor.

Receives ParameterSet percolated down from EDProducer which owns this Builder.
