Example: // Somewhere before DECLARE_METASOUND_DATA_REFERENCE_TYPES(FAudioBuffer...), ParseFrom(int32) is defined // which means this data type can be created from an integer. Metasound::FAudioBuffer ::Metasound::ParseFrom(int32 InNumFrames, const ::Metasound::FOperatorSettings&) { return Metasound::FAudioBuffer(InNumFrames); }
