Detailed Description

Function Documentation

template<typename ForwardIterator , typename Generator >

void bolt::amp::generate	(	bolt::amp::control &	ctl,
		ForwardIterator	first,
		ForwardIterator	last,
		const Generator &	gen
	)

generate assigns to each element of a sequence [first,last] the value returned by gen.

Parameters

ctl	Optional Control structure to control accelerator, debug, tuning, etc.See bolt::amp::control.
first	The first element of the sequence.
last	The last element of the sequence.
gen	A generator, functor taking no parameters.

Template Parameters

ForwardIterator	is a model of Forward Iterator, and ForwardIterator is mutable.
Generator	is a model of Generator, and Generator's result_type is convertible to ForwardIterator's value_type.

The following code snippet demonstrates how to fill a vector with a generator.

#include <bolt/amp/generate.h>
#include <bolt/amp/device_vector.h>
#include <stdlib.h>
...

struct ConstFunctor
{
    int val;
    ConstFunctor(int a) : val(a) {};

    int operator() () const restrict(amp,cpu)
    {
        return val;
    };
};
...

ConstFunctor cf(1);
std::vector<int> vec(1024);
bolt::amp::generate( vec.begin(), vec.end(), cf);

// vec is now filled with 1

template<typename OutputIterator , typename Size , typename Generator >

OutputIterator bolt::amp::generate_n	(	bolt::amp::control &	ctl,
		OutputIterator	first,
		Size	n,
		const Generator &	gen
	)

generate_n assigns to each element of a sequence [first,first+n] the value returned by gen.

Parameters

ctl	Optional Control structure to control accelerator, debug, tuning, etc.See bolt::amp::control.
first	The first element of the sequence.
n	The number of sequence elements to generate.
gen	A generator, functor taking no parameters.

Template Parameters

OutputIterator	is a model of Output Iterator.
Size	is an integral type.
Generator	is a model of Generator, and Generator's result_type is convertible to OutputIterator's value_type.

The following code snippet demonstrates how to fill a vector with a generator.

#include <bolt/amp/generate.h>
#include <bolt/amp/bolt.h>

    ConstFunctor(int a) : val(a) {};

    int operator() () const restrict(amp,cpu)

        return val;
    };
};
...

ConstFunctor cf(1);
std::vector<int> vec(1024);
int n = 1024;
bolt::amp::generate_n(vec.begin(), n, cf);
