class AddressRanges

Declaration

class AddressRanges { /* full declaration omitted */ };

Description

The AddressRanges class helps normalize address range collections. This class keeps a sorted vector of AddressRange objects and can perform insertions and searches efficiently. The address ranges are always sorted and never contain any invalid or empty address ranges. This allows us to emit address ranges into the GSYM file efficiently. Intersecting address ranges are combined during insertion so that we can emit the most compact representation for address ranges when writing to disk.
