print("\n") Prints a newline, and ends it with a newline. Thus two newlines Two options to remove one of them: print() or print("\n", end="") ...
Resolve overload ambiguity with SFINAE
c++,templates,c++11,sfinae,ambiguity
Unfortunately not; SFINAE can be used for selecting between different function template definitions, but not between function overloads passed as an argument. This is because an overloaded function passed as an argument must be resolved to a single overload before dependent types in the template function definition are evaluated and...
Does GHCi not apply the default declaration to resolve type ambiguity?
haskell,types,default,ghci,ambiguity
Does ghci not apply the default declaration to resolve type ambiguity? In GHC 7.8 or greater the Monomorphism Restriction is indeed off inside the GHCi shell, so declarations at the interactive shell will not apply the Num defaulting rules to top level expressions not under a lambda binder (...
Resolve ambiguousness of a base template class member
c++,templates,ambiguity,boost-log
Unfortunately, I could not find a way to replace decltype to something that msvc 2008 could understand to use Petr's answer. Even boost::typeof were not suitable (as long as I used it correctly) So I came with a solution by adding a using case with a macro #include <iostream> #include...
Is it possible to consume a web service in a c++ service application
c++,web-services,service,wsdl,ambiguity
That simply means that you have a name clash in your code, i.e. you have somewhere something like //Header names should be different, just for the sake of the example #include Soap/Wsdlbin/TService.h #include Vcl/Svcmgr/TService.h <some namespace using directives> ... TService service; And the compiler cannot determine which TService it is....
Does D have an equivalent to C++ nullptr_t?
void func(typeof(null)) {} The null literal is a special type in D, which you can specifically get with the typeof operator. Note that this will only catch a null literal - it will not catch a null Object or null pointer variable....
Can the most recent common ancestor in git be ambiguous?
It's not just possible, it's mentioned in the documentation for git merge-base: git merge-base finds best common ancestor(s) between two commits to use in a three-way merge. One common ancestor is better than another common ancestor if the latter is an ancestor of the former. A common ancestor that does...
Warning: direct base class inaccessible in derived due to ambiguity; is this serious?
c++,inheritance,virtual,ambiguity
template <typename T> class ScrollSpell : public T, public SpellFromScroll {}; Here, T = Spell, so the ScrollSpell class has the Spell class as a direct, non-virtual base class, and also as a virtual base class through SpellFromScroll. That is the ambiguity. Declaring the base class T as virtual might...
Ambigous call for operator[] inside a nested class
c++,operator-overloading,nested-class,ambiguity
The operator[] that you defined for your TestClass is in no way "inherited" or somehow "embedded" in your nested class. You can think of C++ nested classes as just ordinary classes, that live in a "nested namespace": TestClass::NestedClass in your sample code. If you want an operator[] for your nested...
Picking the first element using xpath in capybara
You need to surround the entire XPath in parentheses and add the [1] after it. (//div[@id='tree']//a[contains(.,'#{peril}')])[1] ...
Exception org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type is defined: expected single matching bean
java,spring,interface,autowired,ambiguity
That's the expected behavior. Spring has no way to know which specific implementation of the Person interface you want, so it throws that nice exception. Ask for the specific implementation, either: Person person = ctx.getBean(Student.class); or: Person person = ctx.getBean(Professor.class); Or you could also use getBeansOfType() method to retrieve all...
Why is a malformed function used instead of an implicit conversion?
c++,c++11,ambiguity,overload-resolution,malformed
Updated, thanks to @T.C. Wrapper's ctor is a template user-defined conversion, hence the non-template standard conversion sequence overload with Base& takes precedence. The access check is only performed after selecting the overload - which is too late in your case. The complete rules are complicated, more can be found here,...
