Functions

Function thrust::make_constant_iterator

template <typename ValueT,   typename IndexT> __host__ __device__ constant_iterator< ValueT, IndexT > make_constant_iterator(ValueT x,   IndexT i = int()); This version of make_constant_iterator creates a constant_iterator from values given for both value and index. The type of constant_iterator may be inferred by the compiler from the types of its parameters.

Function Parameters:

• x The value of the returned constant_iterator's constant value.
• i The index of the returned constant_iterator within a sequence. The type of this parameter defaults to int. In the default case, the value of this parameter is 0.

Returns: A new constant_iterator with constant value & index as given by x & i.

See: constant_iterator

Function thrust::make_constant_iterator

template <typename V> __host__ __device__ constant_iterator< V > make_constant_iterator(V x); This version of make_constant_iterator creates a constant_iterator using only a parameter for the desired constant value. The value of the returned constant_iterator's index is set to 0.

Function Parameters: x: The value of the returned constant_iterator's constant value.

Returns: A new constant_iterator with constant value equal to x and index equal to 0.

See: constant_iterator

Function thrust::make_counting_iterator

template <typename Incrementable> __host__ __device__ counting_iterator< Incrementable > make_counting_iterator(Incrementable x); make_counting_iterator creates a counting_iterator using an initial value for its Incrementable counter.

Function Parameters: x: The initial value of the new counting_iterator's counter.

Returns: A new counting_iterator whose counter has been initialized to x.

Function thrust::make_discard_iterator

__host__ __device__ discard_iterator make_discard_iterator(discard_iterator<>::difference_type i = discard_iterator<>::difference_type(0)); make_discard_iterator creates a discard_iterator from an optional index parameter.

Function Parameters: i: The index of the returned discard_iterator within a range. In the default case, the value of this parameter is 0.

Returns: A new discard_iterator with index as given by i.

See: constant_iterator

Function thrust::make_permutation_iterator

template <typename ElementIterator,   typename IndexIterator> __host__ __device__ permutation_iterator< ElementIterator, IndexIterator > make_permutation_iterator(ElementIterator e,   IndexIterator i); make_permutation_iterator creates a permutation_iterator from an ElementIterator pointing to a range of elements to “permute” and an IndexIterator pointing to a range of indices defining an indexing scheme on the values.

Function Parameters:

• e An ElementIterator pointing to a range of values.
• i An IndexIterator pointing to an indexing scheme to use on e.

Returns: A new permutation_iterator which permutes the range e by i.

See: permutation_iterator

Function thrust::make_reverse_iterator

template <typename BidirectionalIterator> __host__ __device__ reverse_iterator< BidirectionalIterator > make_reverse_iterator(BidirectionalIterator x); make_reverse_iterator creates a reverse_iterator from a BidirectionalIterator pointing to a range of elements to reverse.

Function Parameters: x: A BidirectionalIterator pointing to a range to reverse.

Returns: A new reverse_iterator which reverses the range x.

Function thrust::make_transform_input_output_iterator

template <typename InputFunction,   typename OutputFunction,   typename Iterator> transform_input_output_iterator< InputFunction, OutputFunction, Iterator > __host__ __device__ make_transform_input_output_iterator(Iterator io,   InputFunction input_function,   OutputFunction output_function); make_transform_input_output_iterator creates a transform_input_output_iterator from an Iterator a InputFunction and a OutputFunction

Function Parameters:

• io An Iterator pointing to where the input to InputFunction will be read from and the result of OutputFunction will be written to
• input_function An InputFunction to be executed on values read from the iterator
• output_function An OutputFunction to be executed on values written to the iterator

Function thrust::make_transform_iterator

template <class AdaptableUnaryFunction,   class Iterator> __host__ __device__ transform_iterator< AdaptableUnaryFunction, Iterator > make_transform_iterator(Iterator it,   AdaptableUnaryFunction fun); make_transform_iterator creates a transform_iterator from an Iterator and AdaptableUnaryFunction.

Function Parameters:

• it The Iterator pointing to the input range of the newly created transform_iterator.
• fun The AdaptableUnaryFunction used to transform the range pointed to by it in the newly created transform_iterator.

Returns: A new transform_iterator which transforms the range at it by fun.

Function thrust::make_transform_output_iterator

template <typename UnaryFunction,   typename OutputIterator> transform_output_iterator< UnaryFunction, OutputIterator > __host__ __device__ make_transform_output_iterator(OutputIterator out,   UnaryFunction fun); make_transform_output_iterator creates a transform_output_iterator from an OutputIterator and UnaryFunction.

Function Parameters:

• out The OutputIterator pointing to the output range of the newly created transform_output_iterator
• fun The UnaryFunction transform the object before assigning it to out by the newly created transform_output_iterator

Function thrust::make_zip_iterator

template <typename... Iterators> __host__ __device__ zip_iterator< thrust::tuple< Iterators... > > make_zip_iterator(thrust::tuple< Iterators... > t); make_zip_iterator creates a zip_iterator from a tuple of iterators.

Function Parameters: t: The tuple of iterators to copy.

Returns: A newly created zip_iterator which zips the iterators encapsulated in t.

See: zip_iterator

Function thrust::make_zip_iterator

template <typename... Iterators> __host__ __device__ zip_iterator< thrust::tuple< Iterators... > > make_zip_iterator(Iterators... its); make_zip_iterator creates a zip_iterator from iterators.

Function Parameters: its: The iterators to copy.

Returns: A newly created zip_iterator which zips the iterators.
