type BoolNotifier ¶

type BoolNotifier interface {
	Notifier
	Value() bool
}

ColorNotifier wraps Notifier with an additional Value() method which returns a bool.

type BytesNotifier ¶

type BytesNotifier interface {
	Notifier
	Value() []byte
}

ColorNotifier wraps Notifier with an additional Value() method which returns a []byte.

type ColorNotifier ¶

type ColorNotifier interface {
	Notifier
	Value() color.Color
}

ColorNotifier wraps Notifier with an additional Value() method which returns a color.Color.

type DurationNotifier ¶

type DurationNotifier interface {
	Notifier
	Value() time.Duration
}

ColorNotifier wraps Notifier with an additional Value() method which returns a time.Duration.

type Float64Notifier ¶

type Float64Notifier interface {
	Notifier
	Value() float64
}

ColorNotifier wraps Notifier with an additional Value() method which returns a float64.

type Float64Value ¶

type Float64Value struct {
	// contains filtered or unexported fields
}

Float64Value implements the Float64Notifier interface and a setter that updates the value and triggers notifications.

func NewFloat64Value(val float64) *Float64Value

func (v *Float64Value) Notify(f func()) Id

func (v *Float64Value) SetValue(val float64)

func (v *Float64Value) Unnotify(id Id)

func (v *Float64Value) Value() float64

type Id ¶

type Id int64

type Int64Notifier ¶

type Int64Notifier interface {
	Notifier
	Value() int64
}

ColorNotifier wraps Notifier with an additional Value() method which returns an int64.

type IntNotifier ¶

type IntNotifier interface {
	Notifier
	Value() int
}

ColorNotifier wraps Notifier with an additional Value() method which returns an int.

type InterfaceNotifier ¶

type InterfaceNotifier interface {
	Notifier
	Value() interface{}
}

ColorNotifier wraps Notifier with an additional Value() method which returns an empty interface.

type Notifier ¶

type Notifier interface {
	Notify(f func()) Id
	Unnotify(id Id)
}

Notifier is the interface the wraps the Notify and Unnotify methods.

Notify stores the function f, and calls in the future it when the object updates. It returns an Id which can be used to stop notifications. Every call to Notify should have a corresponding Unnotify or there could be leaks.

type Relay ¶

type Relay struct {
	// contains filtered or unexported fields
}

Relay implements the Notifier interface, and provides methods for triggering notifications and republishing notifications from other notifiers. It can be embeded into other structs.

func (r *Relay) Notify(f func()) Id

func (r *Relay) Signal()

func (r *Relay) Subscribe(n Notifier)

func (r *Relay) Unnotify(id Id)

func (r *Relay) Unsubscribe(n Notifier)

type StringNotifier ¶

type StringNotifier interface {
	Notifier
	Value() string
}

ColorNotifier wraps Notifier with an additional Value() method which returns a string.

type Uint64Notifier ¶

type Uint64Notifier interface {
	Notifier
	Value() uint64
}

ColorNotifier wraps Notifier with an additional Value() method which returns a uint64.

type UintNotifier ¶

type UintNotifier interface {
	Notifier
	Value() uint
}

ColorNotifier wraps Notifier with an additional Value() method which returns an uint.
