17 | class FileProtocol from IGESData inherits Protocol from IGESData |
18 | |
19 | ---Purpose : This class allows to define complex protocols, in order to |
20 | -- treat various sub-sets (or the complete set) of the IGES Norm, |
21 | -- such as Solid + Draw (which are normally independant), etc... |
22 | -- While it inherits Protocol from IGESData, it admits |
23 | -- UndefinedEntity too |
