Constructor & Destructor Documentation

UnrepeatedRandomizer() [1/2]

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

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

Parameters

min
max

Definition at line 55 of file Random.cpp.

~UnrepeatedRandomizer()

DUtils::Random::UnrepeatedRandomizer::~UnrepeatedRandomizer ( )

inline

Definition at line 122 of file Random.h.

UnrepeatedRandomizer() [2/2]

DUtils::Random::UnrepeatedRandomizer::UnrepeatedRandomizer

(

const UnrepeatedRandomizer &

rnd

)

Copies a randomizer

Parameters

rnd

Definition at line 73 of file Random.cpp.

Member Function Documentation

createValues()

void DUtils::Random::UnrepeatedRandomizer::createValues ( )

protected

Creates the vector with available values

Definition at line 97 of file Random.cpp.

empty()

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

Definition at line 149 of file Random.h.

get()

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

Definition at line 81 of file Random.cpp.

left()

unsigned int DUtils::Random::UnrepeatedRandomizer::left ( ) const

inline

Returns the number of values still to be returned

Returns

amount of values to return

Definition at line 155 of file Random.h.

operator=()

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

(

const UnrepeatedRandomizer &

rnd

)

Copies a randomizer

Parameters

rnd

Definition at line 115 of file Random.cpp.

reset()

void DUtils::Random::UnrepeatedRandomizer::reset

(

)

Resets the randomizer as it were just created

Definition at line 107 of file Random.cpp.

Member Data Documentation

m_max

int DUtils::Random::UnrepeatedRandomizer::m_max

protected

Definition at line 174 of file Random.h.

m_min

int DUtils::Random::UnrepeatedRandomizer::m_min

protected

Min of range of values.

Definition at line 172 of file Random.h.

m_values

std::vector<int> DUtils::Random::UnrepeatedRandomizer::m_values

protected

Available values.

Definition at line 177 of file Random.h.
