Struct Documentation

template<typename Predicate>
struct unary_negate : public thrust::unary_function<Predicate::argument_type, bool>

unary_negate is a function object adaptor: it is an Adaptable Predicate that represents the logical negation of some other Adaptable Predicate. That is: if f is an object of class unary_negate<AdaptablePredicate>, then there exists an object pred of class AdaptablePredicate such that f(x) always returns the same value as !pred(x). There is rarely any reason to construct a unary_negate directly; it is almost always easier to use the helper function not1.
