thrust::binary_negate

Defined in thrust/functional.h

template<typename Predicate>
struct binary_negate

binary_negate is a function object adaptor: it is an Adaptable Binary Predicate that represents the logical negation of some other Adaptable Binary Predicate. That is: if f is an object of class binary_negate<AdaptablePredicate>, then there exists an object pred of class AdaptableBinaryPredicate such that f(x,y) always returns the same value as !pred(x,y). There is rarely any reason to construct a binary_negate directly; it is almost always easier to use the helper function not2.
