Constructor & Destructor Documentation

presh_detectors::presh_detectors ( AlgoPos *  p,
std::string  label 
)

initializes the algorithm

currently, the constructor also builds the various layers of preshower tubes. Rotations & translations generated by this algorithm are the ones used for placing the wedges & sensitive detectors inside the two 'active' layers of the preshower

Member Function Documentation

bool presh_detectors::checkParameters (  )  [virtual]

subclass must check the supplied parameters ParE_, ParS_

whether they are correct and should select this paricular algorithm.

If the parameters are correct by should not select this particular algorithm, checkParamters must return false otherwise true.

The std::string err_ is to be used to be extended with error information in case any errors have been detected. Error information must be attached to err_ because of the possibility of already contained error information.

In case of errors: If an DDException is thrown by the algorithm implementation, further processing of any other implementations of the algorithm will be stopped. If no exception is thrown, checkParamters must return false. It's preferable not to throw an exception in case of errors. The algorithm implementation will throw if all checkParamters() of all registered algorithm implementations have returned false.

Implements AlgoImpl.

int presh_detectors::copyno (  )  const [virtual]

copy-number calculation

In case incr_==0 it makes sense to overload this method, otherwise the invocation-count count_ will be returned as copy-number

If incr_ !=0 the copy-number will be curr_, the actual position in the range [start_,end_,incr_], unless this methods is overloaded.
