bool has_value(int index) const
Returns true if the map has a value associated with the given index, false otherwise.
A mapping of floating-point values per integer index.

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.
Definition: typeHandle.h:85
