template<typename T>
class Array

Public Functions

inline Array(size_t n = 0)

Default constructor

Parameters

n – size of array

inline Array(std::initializer_list<T> l)

inline Array(Array &&other)

Construct in host for device from array

Parameters

• other_arr – array to construct from

• n – size of array Move constructor; this allows the array to be passed as a return value from a function sapping the pointers and keeping the allocated data on the heap.

inline Array(Array &other)

Copy constructor; declaring the move constructor makes compiler implicitly declare the copy constructor deleted

inline ~Array()

Construct in host for device from Array

Parameters

• other – Array to construct from Copy to host from device

• other – Array to construct from Desctructor; dealocate heap and set pointer to null

inline T &operator[](size_t i)

Write access to the array (host)

Parameters

i – index

Returns

reference to i-th element

inline const T &operator[](size_t i) const

Read only access to the array (host)

Parameters

i – index

Returns

reference to i-th element

inline size_t size() const

Get array size

Returns

array size

inline void resize(size_t n)

Resize array droping stored values

Private Members

T *_arr

size_t _size

bool _copied
