| | this function anymore.
| |
| | Example:
| |
| | Directory '@testObj' contains the constructor 'testObj.m' and a function
| | 'fun.m'
| |
| |
| | A subdirectory of '@testObj', named 'private' contains the function
| | 'privFun.m'.
| |
| | 'fun.m' calls only 'privFun.m' in the 'private' subdirectory
| |
| | Test:
| | Create an object:
| |
| | >>x=testObj(<some arguments>)
| |
| |
| | Now, call the private function via fun.m:
| |
| | >>fun(x)
| |
| | Result: Error: privFun.m was not found.
| |
| | Is this only a bug or are private functions not yet provided by octave?
|
| I guess it is a missing feature. I think if you look at
| load-path.{h,cc} and the symbol_table::fcn_info::fcn_info_rep::find
| function in symtab.cc, you'll see that private directories that are
| themselves subdirectories of @ directories aren't considered. This
| isn't an intentional omission, it's just that this case didn't occur
| to me when I implemented the new load path and symbol table code.
OK, this was not too hard to fix. Please try the attached patch.
Thanks,

+ * load-path.h (load_path::dir_info::class_info): New struct.
+ (load_path::dir_info::method_file_map_type): Now a map from
+ class name to a to a class_info object. Change all uses.
+ * load-path.cc (load_path::dir_info::get_method_file_map):
+ Also look for private functions in the class directory.
+ (load_path::add_to_method_map): Also add private functions from
+ class directories to private_fcn_map.
* dirfns.cc (Fmkdir): If directory already exists, return status =
true, but also set error message.
