## Member Function Documentation

virtual void RegionMapperImpl::saveRegionMappings | ( | Writer * | writer | ) | const`[pure virtual]`

| Saves all loaded region defines into `writer.` Note, that result document would not be equal to input one, because there could be multiple input documents. Implemented in StyledHRDMapper, and TextHRDMapper.

virtual void RegionMapperImpl::setRegionDefine | ( | const String & | region,
|  | const RegionDefine * | rdnew
| ) | `[pure virtual]`

  | Changes specified region definition to `rdnew.` Parameters:
  region | Region full qualified name.
  rdnew | New region definition to replace old one
Implemented in StyledHRDMapper, and TextHRDMapper.

const RegionDefine * RegionMapperImpl::enumerateRegionDefines | ( | int | idx | ) | const

| Enumerates all loaded region defines. Returns: RegionDefine with specified internal index, or null if `idx` is too big
