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

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.

Definition at line 31 of file krandom.cpp.

QString KRandom::randomString ( int  length)

Generates a random string.

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

Parameters
lengthGenerate a string of this length.
Returns
the random string

Definition at line 58 of file krandom.cpp.

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.

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
