Detailed Description

Class that sorts electron candidates.

L1GctElectronSorter This class can be constructed to sort iso or non-iso electron candidates. The electrons are sorted in ascending order and the 4 highest in rank will be returned. It represents the 1st stage sorter FPGA's on the electron leaf cards.

void L1GctElectronSorter::setupObjects ( ) [protected, virtual]

Initialise inputs with null objects for the correct bunch crossing if required.

Initialise inputs with null objects for the correct bunch crossing If no other input candidates "arrive", we have the correct bunch crossing to propagate through the processing.

Create a null input electron with the right bunch crossing, and fill the input candidates with copies of this.
