Detailed Description

Pseudo-random number generator.

An implementaiton of the 64-bit MT19937 ("Mersenne Twister") [1] pseudo-random number generator (PRNG). The constructor automatically seeds the PRNG. The implementation was guided by the reference code posted by the authors.

Constructor & Destructor Documentation

GenerateMT() [1/3]

GenerateMT::GenerateMT

(

)

Default constructor.

Seeds the PRNG with a call to the RDTSC instruction.

GenerateMT() [2/3]

sampFiles::GenerateMT::GenerateMT ( const GenerateMT &  old )

default

Copy constructor.

Parameters

[in]

old

object to copy

GenerateMT() [3/3]

sampFiles::GenerateMT::GenerateMT ( GenerateMT &&  old )

default

Move constructor.

Parameters

[in]

old

object to move

Member Function Documentation

operator=() [1/2]

GenerateMT& sampFiles::GenerateMT::operator= ( const GenerateMT &  old )

default

Copy assignment operator.

Parameters

[in]

old

object to copy

operator=() [2/2]

GenerateMT& sampFiles::GenerateMT::operator= ( GenerateMT &&  old )

default

Move assignment.

Parameters

[in]

old

object to move

ranInt()

volatile uint64_t GenerateMT::ranInt ( )

virtual

Generate a pseudo-random 64-bit unsigned integer.

Returns

pseudo-random 64-bit unsigned integer

Implements sampFiles::Generate.
