The concept same_as<T, U> is satisfied if and only if T and U denote the same type. std::same_as<T, U> subsumes std::same_as<U, T> and vice versa. Possible implementation namespace detail { template< class T, class U > concept SameHelper = std::is_same_v<T, U>; } ...
template<class T> struct is_void : std::is_same<void, typename std::remove_cv<T>::type> {}; Example Run this code #include <type_traits> void foo(); static_assert ( std::is_void_v<void> == true and std::is_void_v<const void> == true and std::is_void_v<volatile void>...
If you are using Hazelcast IMDG and C++ Client on the same computer, generally the default configuration should be fine. This is great for trying out the client. However, if you run the client on a different computer than any of the cluster members, you may need to do some simple ...
A piecewise-linear approximation of the function is added to the model. The details of the approximation are controlled using the following four attributes (or using the parameters with the same names): FuncPieces, FuncPieceError, FuncPieceLength, and FuncPieceRatio. Alternatively, the function can...
An implicit barrier exists at the end of the for loop unless the nowait clause is specified.Restrictions are:The for loop must be a structured block, and must not be terminated by a break statement. Values of the loop control expressions must be the same for all iterations of the loop. ...
The size of this member is 16 bits. stream_number The stream_number (synchronization source identifier) is a unique value that identifies a physical stream. Every data packet that belongs to a physical stream contains the same STREAM_NUMBER . The STREAM_NUMBER enables a receiver of multiple...
template<classT>structis_null_pointer:std::is_same<std::nullptr_t,std::remove_cv_t<T>>{}; 注解 对于std::nullptr_t,std::is_pointer是false,因为它不是内建指针类型。 在libc++ 中,std::is_null_pointer不能在 C++11 模式中使用。
