◆ not2()

template<typename BinaryPredicate >
__host__ __device__ binary_negate<BinaryPredicate> thrust::not2 ( const BinaryPredicate &  pred)

not2 is a helper function to simplify the creation of Adaptable Binary Predicates: it takes an Adaptable Binary Predicate pred as an argument and returns a new Adaptable Binary Predicate that represents the negation of pred. That is: if pred is an object of a type which models Adaptable Binary Predicate, then the the type of the result npred of not2(pred) is also a model of Adaptable Binary Predicate and npred(x,y) always returns the same value as !pred(x,y).

Parameters
predThe Adaptable Binary Predicate to negate.
Returns
A new object, npred such that npred(x,y) always returns the same value as !pred(x,y).
Template Parameters
BinaryPredicate is a model of Adaptable Binary Predicate.
