Template Function thrust::any_of(InputIterator, InputIterator, Predicate)

Function Documentation

template<typename InputIterator, typename Predicate>
bool thrust::any_of(InputIterator first, InputIterator last, Predicate pred)

any_of determines whether any element in a range satifies a predicate. Specifically, any_of returns true if pred(*i) is true for any iterator i in the range [first, last) and false otherwise.

bool A[3] = {true, true, false};

thrust::any_of(A, A + 2, thrust::identity<bool>()); // returns true
thrust::any_of(A, A + 3, thrust::identity<bool>()); // returns true

thrust::any_of(A + 2, A + 3, thrust::identity<bool>()); // returns false

// empty range
thrust::any_of(A, A, thrust::identity<bool>()); // returns false
Return

true, if any element satisfies the predicate; false, otherwise.

Parameters

  • first: The beginning of the sequence.

  • last: The end of the sequence.

  • pred: A predicate used to test range elements.
