template<class T>
class utils::FixedArray< T >
A fixed-size array with the size determined at runtime.
The array allows initializing each of the array elements with the same parameters:
class NonDefaultConstructible final {
public:
explicit NonDefaultConstructible(std::string str)
: str_(std::move(str))
{}
std::string GetString() const { return str_; }
private:
std::string str_;
};
ASSERT_EQ(array.size(), 42);
ASSERT_EQ(array[0].GetString(), "The string");
ASSERT_EQ(array[14].GetString(), "The string");
ASSERT_EQ(array[41].GetString(), "The string");
The array also allows initializing each of the array elements with the output of a generator function:
using NonMovable = std::atomic<std::size_t>;
constexpr std::size_t kObjectCount = 42;
EXPECT_EQ(array.size(), kObjectCount);
EXPECT_FALSE(array.empty());
std::size_t index = 0;
for (const auto& item : array) {
EXPECT_EQ(item.load(), index++);
}
EXPECT_EQ(index, kObjectCount);
