Functions

Function thrust::operator==

template <typename T1,   typename T2> __host__ __device__ bool operator==(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for equality.

Template Parameters:

• T1 is a model of Equality Comparable.
• T2 is a model of Equality Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if x.first == y.first && x.second == y.second.

Function thrust::operator<

template <typename T1,   typename T2> __host__ __device__ bool operator<(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for ascending ordering.

Template Parameters:

• T1 is a model of LessThan Comparable.
• T2 is a model of LessThan Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if x.first < y.first || (!(y.first < x.first) && x.second < y.second).

Function thrust::operator!=

template <typename T1,   typename T2> __host__ __device__ bool operator!=(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for inequality.

Template Parameters:

• T1 is a model of Equality Comparable.
• T2 is a model of Equality Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if !(x == y).

Function thrust::operator>

template <typename T1,   typename T2> __host__ __device__ bool operator>(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for descending ordering.

Template Parameters:

• T1 is a model of LessThan Comparable.
• T2 is a model of LessThan Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if y < x.

Function thrust::operator<=

template <typename T1,   typename T2> __host__ __device__ bool operator<=(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for ascending ordering or equivalence.

Template Parameters:

• T1 is a model of LessThan Comparable.
• T2 is a model of LessThan Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if !(y < x).

Function thrust::operator>=

template <typename T1,   typename T2> __host__ __device__ bool operator>=(const pair< T1, T2 > & x,   const pair< T1, T2 > & y); This operator tests two pairs for descending ordering or equivalence.

Template Parameters:

• T1 is a model of LessThan Comparable.
• T2 is a model of LessThan Comparable.

Function Parameters:

• x The first pair to compare.
• y The second pair to compare.

Returns: true if and only if !(x < y).

Function thrust::swap

template <typename T1,   typename T2> __host__ __device__ void swap(pair< T1, T2 > & x,   pair< T1, T2 > & y); swap swaps the contents of two pairs.

Function Parameters:

• x The first pair to swap.
• y The second pair to swap.

Function thrust::make_pair

template <typename T1,   typename T2> __host__ __device__ pair< T1, T2 > make_pair(T1 x,   T2 y); This convenience function creates a pair from two objects.

Template Parameters:

• T1 There are no requirements on the type of T1.
• T2 There are no requirements on the type of T2.

Function Parameters:

• x The first object to copy from.
• y The second object to copy from.

Returns: A newly-constructed pair copied from a and b.
