Libraries.Compute.Random

The Random class permits generation of pseudorandom numbers that can be used for a variety of applications.

Example Code

use Libraries.Compute.Random

class Main
    action Main
        // Print a list of ten random integers, each within the range 5 to 9.
        Random random
        repeat 10 times
            output random:RandomIntegerBetween(5, 9)
        end
    end
end

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

This action determines if two objects are equal based on their hash code values.

Example Code

use Libraries.Language.Object
        use Libraries.Language.Types.Text
        Object o
        Text t
        boolean result = o:Equals(t)

This action gets the hash code for an object.

Example Code

Object o
        integer hash = o:GetHashCode()

This action returns a random boolean value. (True or False)

Example Code

use Libraries.Compute.Random
    Random random
    boolean randomBool = random:RandomBoolean()

This action returns a random integer within the range 0 to +2,147,483,646 (lower bound inclusive, upper bound inclusive).

Example Code

use Libraries.Compute.Random
    Random random
    integer randomNumber = random:RandomInteger()

This action returns a random integer that is between zero (inclusive) and +2,147,483,646 (inclusive).

Example Code

use Libraries.Compute.Random
    Random random
    integer randomNumber = random:RandomInteger(5)

This action returns a random integer between minimum and maximum. Minimum and maximum are inclusive.

Example Code

use Libraries.Compute.Random
    Random random
    integer randomNumber = random:RandomIntegerBetween(1, 5)

This action returns a list of randomly generated integers in the range 0 to +2,147,483,646 (lower bound inclusive, upper bound inclusive).

Example Code

use Libraries.Compute.Random
    use Libraries.Containers.List
    Random random
    List<Integer> list
    list = random:RandomListOfIntegers(15)

This action returns a list of randomly generated numbers in the range 0 to 1.

Example Code

use Libraries.Compute.Random
    use Libraries.Containers.List
    Random random
    List<number> list
    list = random:RandomListOfNumbers(15)

This action returns a random number within the range 0 to 1.

Example Code

use Libraries.Compute.Random
    Random random
    number randomNumber = random:RandomNumber()

This action sets the seed used to generate random numbers. On creation of a Random object, the seed is set to the current system time in milliseconds.

Example Code

use Libraries.Compute.Random
    Random random
    random:SetSeed(1010001) // set the seed to 1010001
