func NewNumberGenerator

func NewNumberGenerator() NumberGenerator

NewNumberGenerator returns a new number generator object that implements the NumberGenerator interface.

type StringGenerator

type StringGenerator interface {
	GenerateFromSource(source string, length int) string
}

StringGenerator is the interface that describes a string generator object.

func NewStringGenerator

func NewStringGenerator() StringGenerator

NewStringGenerator returns a new string generator object that implements the StringGenerator interface.
