Detailed Description

This utility class is intended to provide a standard way to set restrictions on the HcalTopology to exclude cells for testbeam and other purposes. It functions as a parser to convert textually-encoded restrictions into calls to HcalTopology::exclude().

The grammer is (using a rough notation)

line = rule >> *(; >> rule ) rule = region | subdetector region = subdetname ieta1 ieta2 iphi1 iphi2 [depth1 depth2] subdetector = subdetname subdetname = "HB" | "HE" | "HO" | "HF"

Parses a line of restrictions and returns an error string if there is a problem. The line must be formated as described in the class description.
