Overview

Package bindings provides bindings for values.

Version 0.2.0.

• type Float64Listener

Types

type Boolean

type Boolean interface {
	AddListener(BooleanListener)
	And(Boolean) Boolean
	EqualTo(Boolean) Boolean
	Not() Boolean
	NotEqualTo(Boolean) Boolean
	Or(Boolean) Boolean
	RemoveListener(BooleanListener)
	Set(bool)
	Value() bool
}

Boolean is an observable value.

func NewBoolean

func NewBoolean() Boolean

NewBoolean creates the observable Boolean and returns it.

type BooleanListener

type BooleanListener interface {
	BooleanChanged(Boolean, bool, bool)
}

BooleanListener is a listener for the observable Boolean. Function BooleanChanged is called only when observable value has changed, i.e. new value is not equal to old value.

type Float64

type Float64 interface {
	AddListener(Float64Listener)
	Divide(Float64) Float64
	EqualTo(Float64) Boolean
	GreaterThan(Float64) Boolean
	GreaterThanOrEqualTo(Float64) Boolean
	LessThan(Float64) Boolean
	LessThanOrEqualTo(Float64) Boolean
	Minus(Float64) Float64
	Multiply(Float64) Float64
	NotEqualTo(Float64) Boolean
	Plus(Float64) Float64
	RemoveListener(Float64Listener)
	Set(float64)
	Value() float64
}

Float64 is an observable value.

type Float64Listener

type Float64Listener interface {
	Float64Changed(Float64, float64, float64)
}

Float64Listener is a listener for the observable Float64. Function Float64Changed is called only when observable value has changed, i.e. new value is not equal to old value.
