Detailed Description

template<bool _Unsigned = true, bool _Exact_Size = false>
class Givaro::RandomIntegerIterator< _Unsigned, _Exact_Size >

Random Integer Iterator.

Generates integers of specified length.

Template Parameters

_Unsigned	if true, then only non negative integers are generated, if false, their sign is random.
_Exact_Size	if true, then random integers have exactly the number of required bits, if false, they have less than the required number of bits WARNING, the seed is *** global *** WARNING: i.e. sets the seed for all Givaro Integer

Constructor & Destructor Documentation

RandomIntegerIterator() [1/3]

RandomIntegerIterator ( const Integer_Domain &  D, uint64_t  seed = 0  )

inline

Constructor.

Parameters

seed	if 0 a seed will be generated, otherwise, the provided seed will be used, *** globally *** Default bit size (30) can be changed with method 'setBitsize'

RandomIntegerIterator() [2/3]

RandomIntegerIterator ( const Integer_Domain &  D, uint64_t  seed, const Integer &  samplesize  )

inline

Constructor.

Parameters

seed	if 0 a seed will be generated, otherwise, the provided seed will be used, *** globally ***
samplesize	is number ofpossible random values

RandomIntegerIterator() [3/3]

RandomIntegerIterator ( const RandomIntegerIterator< _Unsigned, _Exact_Size > &  R )

inline

copy constructor.

Parameters

R	random iterator to be copied.

Member Function Documentation

operator=()

RandomIntegerIterator& operator= ( const RandomIntegerIterator< _Unsigned, _Exact_Size > &  R )

inline

copy.

Parameters

R	random iterator to be copied.

operator*()

const Integer_Type& operator* ( ) const

inline

get the random integer.

returns the actual integer.

randomInteger()

returns the actual integer.

Warning

a new integer is not generated.

setSeed()

static void setSeed ( uint64_t  ul )

inlinestatic

Sets the seed *** globally *** WARNING: i.e.

sets the seed for all Givaro Integer Set the random seed to be ul.

Parameters

ul	the new seed.
