Most methods of the “Group” class are exactly the same as the ones defined in the Group class of ruby extension (Chapter I.3). Several methods or properties are different however:
The iterators are now “iter_element”, “iter_rbe”, “iter_node” and “iter_coordsys” instead of “each_element”, “each_rbe”, “each_node” and “each_coordsys”.
The “toBlob” and “fromBlob” methods deal with Array of Bytes (unsigned char) instead of Strings in the ruby extension.
The “Clone” method returns a copy of the object.
