◆ getImplName()

const char * Random::getImplName ( )
static

Definition at line 79 of file Random.cxx.

◆ getRandom() [1/2]

int Random::getRandom ( )
static

Returns a postive integer (31 bits) of randomness.

Implementation is platform dependent.

Definition at line 261 of file Random.cxx.

◆ getRandom() [2/2]

Data Random::getRandom ( unsigned int  numBytes)
static

Definition at line 355 of file Random.cxx.

◆ getRandomBase64()

Data Random::getRandomBase64 ( unsigned int  numBytes)
static

Definition at line 388 of file Random.cxx.

◆ getRandomHex()

Data Random::getRandomHex ( unsigned int  numBytes)
static

Definition at line 382 of file Random.cxx.

◆ getSimpleSeed()

unsigned Random::getSimpleSeed ( )
static

Key goal is to make sure that each thread has distinct seed.

Definition at line 102 of file Random.cxx.

◆ getVersion4UuidUrn()

Data Random::getVersion4UuidUrn ( )
static

Returns a version 4 (random) UUID as defined in RFC 4122.

Todo:
This is something of a suboptimal hack. Ideally, we would encapsulate UUID as its own class, with options to create any of versions 1 through 5 (and Nil UUIDs). This class would have various access methods to pull the result out as a bitstring, as raw data, as a URN, etc. For what I need to do right now, however, version 4 UUIDs get me where I need to go. <abr>

◆ initialize()

void Random::initialize ( )
static

ah! blocks if /dev/random on embedded sys
