Struct Documentation¶

template<typename T1, typename T2> struct project2nd¶

project2nd is a function object that takes two arguments and returns its second argument; the first argument is unused. It is essentially a generalization of identity to the case of a Binary Function.

#include <thrust/functional.h>
#include <assert.h>
...
int x =  137;
int y = -137;
thrust::project2nd<int> pj2;
assert(y == pj2(x,y));

typedef second_argument_type¶: The type of the function object’s second argument.

typedef result_type¶: The type of the function object’s result;.

Public Functions

__host__ __device__ const T2& thrust::project2nd::operator()(const T1 &, const T2 & rhs) const: Function call operator. The return value is rhs.
