Most FeResPost managed classes implement the “ICloneable” interface and define a “Clone” method that corresponds to ruby “clone” method in FeResPost ruby extension. “Post” static class does not derive from ICloneable, as this class can not be instantiated. Also, the classes deriving from “DataBase” (“NastranDb” and “SamcefDb” classes) do not implement the “Clone” method.
The “to_s” method of ruby extension are replaced by “ToString” method in .NET assembly.
