Constructor & Destructor Documentation

DUtils::Random::UnrepeatedRandomizer::UnrepeatedRandomizer	(	int	min,
		int	max
	)

Creates a randomizer that returns numbers in the range [min, max]

Parameters:

	min
	max

DUtils::Random::UnrepeatedRandomizer::UnrepeatedRandomizer

(

const UnrepeatedRandomizer &

rnd

)

Copies a randomizer

Parameters:

rnd

Member Function Documentation

void DUtils::Random::UnrepeatedRandomizer::createValues

(

)

[protected]

Creates the vector with available values

bool DUtils::Random::UnrepeatedRandomizer::empty

(

)

const [inline]

Returns whether all the possible values between min and max were already given. If get() is called when empty() is true, the behaviour is the same than after creating the randomizer

Returns:

true iff all the values were returned

int DUtils::Random::UnrepeatedRandomizer::get

(

)

Returns a random number not given before. If all the possible values were already given, the process starts again

Returns:

unrepeated random number

unsigned int DUtils::Random::UnrepeatedRandomizer::left

(

)

const [inline]

Returns the number of values still to be returned

Returns:

amount of values to return

DUtils::Random::UnrepeatedRandomizer & DUtils::Random::UnrepeatedRandomizer::operator=

(

const UnrepeatedRandomizer &

rnd

)

Copies a randomizer

Parameters:

rnd

void DUtils::Random::UnrepeatedRandomizer::reset

(

)

Resets the randomizer as it were just created
