Types

type TRandomArray

type TRandomArray struct{}

Random generator for array objects.

Examples:

value1 := RandomArray.pick([1, 2, 3, 4]); // Possible result: 3
var RandomArray *TRandomArray = &TRandomArray{}

func (*TRandomArray) Pick

func (c *TRandomArray) Pick(value interface{}) interface{}

Picks a random element from specified array. Parameters:

  • values: an array of any interface

Returns a randomly picked item.

type TRandomBoolean

type TRandomBoolean struct{}

Random generator for boolean values.

Example:

value1 := RandomBoolean.nextBoolean();    // Possible result: true
value2 := RandomBoolean.chance(1,3);      // Possible result: false
var RandomBoolean *TRandomBoolean = &TRandomBoolean{}

func (*TRandomBoolean) Chance

func (c *TRandomBoolean) Chance(chances int, maxChances int) bool
