Class generator

class generator<T, VecWidth, Class, Twork> base

template <typename T, size_t VecWidth, typename Class, typename Twork = T>
struct generator : public expression_traits_defaults { … }

CRTP base for stateful streaming generators that produce fixed-width vectors of values on demand.

Generators are expressions of infinite length and are not random-access.

Template parameters
T Value type produced by the generator.
VecWidth Native vector width used by the generator.
Class Derived generator type (CRTP).
Twork Working type used to store the internal state; defaults to T but may differ (e.g. interleaved cos/sin pairs for gen_sin ).

function resync(T) 

void resync(T start) const

Reinitializes the generator state so that the next produced value corresponds to the given start.

Parameters
start Starting value to synchronize the generator to.

function generate() 

template <size_t N>
KFR_MEM_INTRINSIC vec<T, N> generate() const

Produces a vector of N values from the generator and advances its internal state.

Template parameters
N Number of values to produce.
Returns
Vector of N generated values.
