Class Documentation

template<typename T, typename Alloc = thrust::device_malloc_allocator<T>>
class device_vector : public detail::vector_base<T, Alloc>

A device_vector is a container that supports random access to elements, constant time removal of elements at the end, and linear time insertion and removal of elements at the beginning or in the middle. The number of elements in a device_vector may vary dynamically; memory management is automatic. The memory associated with a device_vector resides in the memory space of a parallel device.

Public Functions

__host__ device_vector(void)

This constructor creates an empty device_vector.

__host__ ~device_vector(void)

The destructor erases the elements.

__host__ device_vector(size_type n)

This constructor creates a device_vector with the given size.

Parameters

  • n: The number of elements to initially create.

__host__ device_vector(size_type n, const value_type &value)

This constructor creates a device_vector with copies of an exemplar element.

Parameters

  • n: The number of elements to initially create.

  • value: An element to copy.

__host__ device_vector(const device_vector &v)

Copy constructor copies from an exemplar device_vector.

Parameters

__host__ device_vector& thrust::device_vector::operator=(const device_vector & v)

Copy assign operator copies another device_vector with the same type.

Parameters

template<typename OtherT, typename OtherAlloc>__host__ __device__ thrust::device_vector::device_vector(const device_vector < OtherT, OtherAlloc > & v)

Copy constructor copies from an exemplar device_vector with different type.

Parameters

template<typename OtherT, typename OtherAlloc>__host__ device_vector& thrust::device_vector::operator=(const device_vector < OtherT, OtherAlloc > & v)

Assign operator copies from an exemplar device_vector with different type.

Parameters

template<typename OtherT, typename OtherAlloc>
__host__ device_vector(const std::vector<OtherT, OtherAlloc> &v)

Copy constructor copies from an exemplar std::vector.

Parameters

  • v: The std::vector to copy.

template<typename OtherT, typename OtherAlloc>__host__ device_vector& thrust::device_vector::operator=(const std::vector< OtherT, OtherAlloc > & v)

Assign operator copies from an exemplar std::vector.

Parameters

  • v: The std::vector to copy.

template<typename OtherT, typename OtherAlloc>
__host__ device_vector(const host_vector<OtherT, OtherAlloc> &v)

Copy constructor copies from an exemplar host_vector with possibly different type.

Parameters

template<typename OtherT, typename OtherAlloc>__host__ device_vector& thrust::device_vector::operator=(const host_vector < OtherT, OtherAlloc > & v)

Assign operator copies from an examplar host_vector.

Parameters

template<typename InputIterator>
__host__ device_vector(InputIterator first, InputIterator last)

This constructor builds a device_vector from a range.

Parameters

  • first: The beginning of the range.

  • last: The end of the range.
