[R] R rtypecheck typemaps
|
|
|
|
Further switch to use rtypecheck typemaps instead of hard coded logic.
|
|
The full switch to typemaps is deferred until swig-4.2 as it can't be fully
|
|
backwards compatible. For now a warning is provided to help the
|
|
transition. It provides the full typemap that should be placed into
|
|
a user's interface file, for example:
|
|
|
|
%typemap("rtype") int32_t * "integer"
|
|
void testmethod(int32_t * i);
|
|
void testmethod();
|
|
|
|
If there is no rtypecheck typemap for int32_t *, the warning shown is:
|
|
|
|
example.i:7: Warning 750: Optional rtypecheck code is deprecated. Add the
|
|
following typemap to fix as the next version of SWIG will not work without it:
|
|
%typemap("rtypecheck") int32_t * %{ (is.integer($arg) || is.numeric($arg)) %}
|
|
|
|
The warning is shown for any code that previously used "numeric", "integer" or
|
|
"character" for the rtype typemap. Copying the rtypecheck typemap as
|
|
shown into the user interface file will provide the appropriate fix and
|
|
the warning will disappear. This is important to do as swig-4.2 will
|
|
not be able to provide this helpful warning.

[R] Allow NULL to be used in overloaded functions taking shared_ptr.
|
|
Also fixes special variable $argtype expansion in rtypecheck typemaps.

|
|
[R] Improve R wrapper error message when calling overloaded methods
|
|
when incorrect types passed are passed to the overloaded methods.
|
|
|
|
Old unhelpful error message:
|
|
Error in f(...) : could not find function "f"
|
|
|
|
Example of new improved error message:
|
|
Error in use_count(k) :
|
|
cannot find overloaded function for use_count with argtypes (NULL)
