hitfit::Fit_Result_Vec Class Reference

Holds pointers to a set of Fit_Result objects, resulting from different jet permutation with some consistent selection. The results are ordered by increasing values. A maximum length for the list of Fit_Result objects may be specified; when new results, those with the largest value fall off the end. More...

Detailed Description

Holds pointers to a set of Fit_Result objects, resulting from different jet permutation with some consistent selection. The results are ordered by increasing values. A maximum length for the list of Fit_Result objects may be specified; when new results, those with the largest value fall off the end.

The Fit_Result object are reference counted, in order to allow then to be entered in multiple vectors.
