thrust::swap

Defined in thrust/swap.h

template<typename Assignable1, typename Assignable2>
inline void thrust::swap(Assignable1 &a, Assignable2 &b)

swap assigns the contents of a to b and the contents of b to a. This is used as a primitive operation by many other algorithms.

The following code snippet demonstrates how to use swap to swap the contents of two variables.

#include <thrust/swap.h>
...
int x = 1;
int y = 2;
thrust::swap(x,h);

// x == 2, y == 1

Parameters

  • a – The first value of interest. After completion, the value of b will be returned here.

  • b – The second value of interest. After completion, the value of a will be returned here.

Template Parameters

Assignable – is a model of Assignable.
