Note that the %rename directive currently does not parse the double quotes, so these can't be easily accessed from
target languages.
Like other operators that SWIG parses, a warning is given about renaming the operator in order for it to be wrapped:
</p>
<div class="shell"><pre>
example.i:27: Warning 503: Can't wrap 'operator "" _myRawLiteral' unless renamed to a valid identifier.
</pre></div>
<p>
Use of user-defined literals such as the following still give a syntax error:
If %rename is used, then it can be called like any other wrapped method.
Currently you need to specify the full declaration including parameters for %rename:
</p>
<div class="code"><pre>
%rename(MyRawLiteral) operator"" _myRawLiteral(const char * value);
</pre></div>
<p>
Or if you just wish to ignore it altogether:
</p>
<div class="code"><pre>
%ignore operator "" _myRawLiteral(const char * value);
</pre></div>
