But now, with shared_ptr, I cannot assign or evaluate to 0. I understand that the default ErrorWriterPtr constructor and ErrorWriterPtr.reset() will provide me with an empty pointer that I can check.
Instead of
if (writer_.get() == 0) { /* create default error writer */ } Why not just use if ( !writer_ ) { /* create default error writer */ } instead? This would work with ordinary pointers too.
What is the equivalent to:
Parser testParser(0);
Parser testParser( ErrorWriterPtr() ); // would work I'd be tempted instead to replace the constructor definition with Parser(ErrorWriterPtr writer = ErrorWritePtr()) : writer_(writer) { } however, to be able to just say Parser testParser; if you don't want to specify the writer. ~ Scott McMurray
