Functions

template<typename Iterator> constexpr HPX_CXX_EXPORT bool insert_checked (std::pair< Iterator, bool > const &r) noexcept

Helper function for writing predicates that test whether an std::map insertion succeeded. This inline template function negates the need to explicitly write the sometimes lengthy std::pair<Iterator, bool> type.

Parameters

r – [in] The return value of a std::map insert operation.

Returns

This function returns r.second.

template<typename Iterator> HPX_CXX_EXPORT bool insert_checked (std::pair< Iterator, bool > const &r, Iterator &it)

Helper function for writing predicates that test whether an std::map insertion succeeded. This inline template function negates the need to explicitly write the sometimes lengthy std::pair<Iterator, bool> type.

Parameters

  • r – [in] The return value of a std::map insert operation.

  • r – [out] A reference to an Iterator, which is set to r.first.

  • it – [out] on exit, will hold the iterator referring to the inserted element

Returns

This function returns r.second.
