Types ¶
type ConstantRand ¶
type ConstantRand struct {
// contains filtered or unexported fields
}
ConstantRand implements a constant random generator. This generator returns the defined seed every time, unless a method has a bound then it returns at most the given bound. It is therefore not random at all and can be safely used when deterministic values are needed.
func NewConstantRand ¶
func NewConstantRand(seed int64) *ConstantRand
NewConstantRand returns a new instance of the constant random generator
func (*ConstantRand) Int ¶
func (r *ConstantRand) Int() int
Int returns a non-negative pseudo-random int
func (*ConstantRand) Int63 ¶
func (r *ConstantRand) Int63() int64
Int63 returns a non-negative pseudo-random 63-bit integer as an int64.
func (*ConstantRand) Int63n ¶
func (r *ConstantRand) Int63n(n int64) int64
Int63n returns, as an int64, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func (*ConstantRand) Intn ¶
func (r *ConstantRand) Intn(n int) int
Intn returns, as an int, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func (*ConstantRand) Seed ¶
func (r *ConstantRand) Seed(seed int64)
Seed uses the provided seed value to initialize the generator to a deterministic state.
type IncrementRand ¶
type IncrementRand struct {
// contains filtered or unexported fields
}
IncrementRand implements an incrementing random generator. This generator returns beginning from 0 an incremented value on every call. If the defined seed is equal or greater to the current generator value, the generator resets its value to 0. The generator will reset itself also to zero, if a method has a bound and the current generator value is equal or greater to the bound.
func NewIncrementRand ¶
func NewIncrementRand(seed int64) *IncrementRand
NewIncrementRand returns a new instance of the increment random generator
func (*IncrementRand) Int ¶
func (r *IncrementRand) Int() int
Int returns a non-negative pseudo-random int
func (*IncrementRand) Int63 ¶
func (r *IncrementRand) Int63() int64
Int63 returns a non-negative pseudo-random 63-bit integer as an int64.
func (*IncrementRand) Int63n ¶
func (r *IncrementRand) Int63n(n int64) int64
Int63n returns, as an int64, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func (*IncrementRand) Intn ¶
func (r *IncrementRand) Intn(n int) int
Intn returns, as an int, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
func (*IncrementRand) Seed ¶
func (r *IncrementRand) Seed(seed int64)
Seed uses the provided seed value to initialize the generator to a deterministic state.
type Rand ¶
type Rand interface {
// Int returns a non-negative pseudo-random int
Int() int
// Intn returns, as an int, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
Intn(n int) int
// Int63 returns a non-negative pseudo-random 63-bit integer as an int64.
Int63() int64
// Int63n returns, as an int64, a non-negative pseudo-random number in [0,n). It panics if n <= 0.
Int63n(n int64) int64
// Seed uses the provided seed value to initialize the generator to a deterministic state.
Seed(seed int64)
}
Rand defines random data generator for the Tavor framework
