Types

type Boolean

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

Boolean is an observable value.

func NewBoolean

func NewBoolean(params ...interface{}) Boolean

NewBoolean creates the observable Boolean and returns it.

type BooleanFilter

type BooleanFilter interface {
	FilterBoolean(Boolean, bool, bool) bool
}

BooleanFilter provides a function that is called before setting the value of Boolean.

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 Float32

type Float32 interface {
	AddListener(Float32Listener)
	Divide(Float32) Float32
	EqualTo(Float32) Boolean
	Float64() Float64
	GreaterThan(Float32) Boolean
	GreaterThanOrEqualTo(Float32) Boolean
	Int() Int
	LessThan(Float32) Boolean
	LessThanOrEqualTo(Float32) Boolean
	Minus(Float32) Float32
	Multiply(Float32) Float32
	NotEqualTo(Float32) Boolean
	Plus(Float32) Float32
	RemoveListener(Float32Listener)
	Set(float32)
	SetFilter(Float32Filter)
	String() String
	Value() float32
}

Float32 is an observable value.

func NewFloat32

func NewFloat32(params ...interface{}) Float32

NewFloat32 creates the observable Float32 and returns it.

type Float32Filter

type Float32Filter interface {
	FilterFloat32(Float32, float32, float32) float32
}

Float32Filter provides a function that is called before setting the value of Float32.

type Float32Listener

type Float32Listener interface {
	Float32Changed(Float32, float32, float32)
}

Float32Listener is a listener for the observable Float32. Function Float32Changed 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
	Float32() Float32
	GreaterThan(Float64) Boolean
	GreaterThanOrEqualTo(Float64) Boolean
	Int() Int
	LessThan(Float64) Boolean
	LessThanOrEqualTo(Float64) Boolean
	Minus(Float64) Float64
	Multiply(Float64) Float64
	NotEqualTo(Float64) Boolean
	Plus(Float64) Float64
	RemoveListener(Float64Listener)
	Set(float64)
	SetFilter(Float64Filter)
	String() String
	Value() float64
}

Float64 is an observable value.

func NewFloat64

func NewFloat64(params ...interface{}) Float64

NewFloat64 creates the observable Float64 and returns it.

type Float64Filter

type Float64Filter interface {
	FilterFloat64(Float64, float64, float64) float64
}

Float64Filter provides a function that is called before setting the value of Float64.

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.

type Int

type Int interface {
	AddListener(IntListener)
	Divide(Int) Int
	EqualTo(Int) Boolean
	Float64() Float64
	Float32() Float32
	GreaterThan(Int) Boolean
	GreaterThanOrEqualTo(Int) Boolean
	LessThan(Int) Boolean
	LessThanOrEqualTo(Int) Boolean
	Minus(Int) Int
	Multiply(Int) Int
	NotEqualTo(Int) Boolean
	Plus(Int) Int
	RemoveListener(IntListener)
	Set(int)
	SetFilter(IntFilter)
	String() String
	Value() int
}

Int is an observable value.

func NewInt

func NewInt(params ...interface{}) Int

NewInt creates the observable Int and returns it.

type IntFilter

type IntFilter interface {
	FilterInt(Int, int, int) int
}

IntFilter provides a function that is called before setting the value of Int.

type IntListener

type IntListener interface {
	IntChanged(Int, int, int)
}

IntListener is a listener for the observable Int. Function IntChanged is called only when observable value has changed, i.e. new value is not equal to old value.

type String

type String interface {
	AddListener(StringListener)
	Append(String) String
	Boolean() Boolean
	EqualTo(String) Boolean
	Float64() Float64
	Float32() Float32
	GreaterThan(String) Boolean
	GreaterThanOrEqualTo(String) Boolean
	Int() Int
	LessThan(String) Boolean
	LessThanOrEqualTo(String) Boolean
	LowerCase() String
	NotEqualTo(String) Boolean
	RemoveListener(StringListener)
	Set(string)
	SetFilter(StringFilter)
	Value() string
}

String is an observable value.

func NewString

func NewString(params ...interface{}) String

NewString creates the observable String and returns it.

type StringFilter

type StringFilter interface {
	FilterString(String, string, string) string
}

StringFilter provides a function that is called before setting the value of String.

type StringListener

type StringListener interface {
	StringChanged(String, string, string)
}

StringListener is a listener for the observable String. Function StringChanged is called only when observable value has changed, i.e. new value is not equal to old value.
