Detailed Description

Helper class to create random data.

This namespace provides methods which generate random data. KRandom is not recommended for serious random-number generation needs, like cryptography.

Function Documentation

random()

int KRandom::random

(

)

Generates a uniform random number.

Returns

A random number in the range [0, RAND_MAX). The RNG is seeded on first use.

Deprecated:

Since 5.72, use QRandomGenerator::global(). The 1:1 port is bounded(RAND_MAX) but check all the methods that QRandomGenerator provides.

randomString()

QString KRandom::randomString

(

int

length

)

Generates a random string.

It operates in the range [A-Za-z0-9]

Parameters

length

Generate a string of this length.

Returns

the random string

shuffle() [1/2]

template<typename T >

void KRandom::shuffle

(

T &

container

)

Reorders the elements of the given container randomly.

The container needs to implement size() and T &operator[]

Since

5.73

Definition at line 80 of file krandom.h.

shuffle() [2/2]

template<typename T >

void KRandom::shuffle	(	T &	container,
		QRandomGenerator *	generator
	)

Reorders the elements of the given container randomly using the given random number generator.

The container needs to implement size() and T &operator[]

Since

5.73

Definition at line 62 of file krandom.h.
