bool has_tag(int polygon_index) const
Returns true if the map has a tag associated with the given polygon index, false otherwise.
int get_tag(int polygon_index) const
Returns the tag associated with the given polygon index, or -1 if there is no tag associated.
virtual bool read_iff(IffInputFile *in, size_t stop_at)
Reads the data of the chunk in from the given input file, if possible.
TypeHandle is the identifier used to differentiate C++ class types.
