Template Struct bit_and

Struct Documentation

template<typename T>
struct bit_and

bit_and is a function object. Specifically, it is an Adaptable Binary Function. If f is an object of class bit_and<T>, and x and y are objects of class T, then f(x,y) returns x&y.

The following code snippet demonstrates how to use

bit_and to take the bitwise AND of one device_vector of ints by another.
Template Parameters

  • T: is a model of Assignable, and if x and y are objects of type T, then x&y must be defined and must have a return type that is convertible to T.

#include <thrust/device_vector.h>
#include <thrust/functional.h>
#include <thrust/sequence.h>
#include <thrust/fill.h>
#include <thrust/transform.h>
...
const int N = 1000;
thrust::device_vector<int> V1(N);
thrust::device_vector<int> V2(N);
thrust::device_vector<int> V3(N);

thrust::sequence(V1.begin(), V1.end(), 1);
thrust::fill(V2.begin(), V2.end(), 13);

thrust::transform(V1.begin(), V1.end(), V2.begin(), V3.begin(),
                  thrust::bit_and<int>());
// V3 is now {1&13, 2&13, 3&13, ..., 1000%13}
