This base class version simply returns 0, but a derived class should override this function if it needs to construct and run a NxsSetReader object to read a set involving taxa. The NxsSetReader object may need to use this function to look up a taxon label encountered in the set. A class that overrides this method should return the taxon index in the range [1..ntax]. Reimplemented in NxsAssumptionsBlock, and NxsCharactersBlock. Definition at line 509 of file nxsblock.cpp. |
