func NewByOption(opts ...Option) Message

func NewByOptionWithoutID

func NewByOptionWithoutID(id int, opts ...Option) Message

func (Message) String

func (msg Message) String()

type MinusOperator

type MinusOperator struct {
	*OperatorBase
}

MinusOperator Operator 的实际减法实现

func (MinusOperator) Result

func (o MinusOperator) Result() int

Result 获取结果

type MinusOperatorFactory

type MinusOperatorFactory struct{}

MinusOperatorFactory 是 MinusOperator 的工厂类

func (MinusOperatorFactory) Create

func (MinusOperatorFactory) Create() Operator

type Operator

type Operator interface {
	SetA(int)
	SetB(int)
	Result() int
}

Operator 是被封装的实际类接口

type OperatorBase

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

OperatorBase 是Operator 接口实现的基类，封装公用方法

func (*OperatorBase) SetA

func (o *OperatorBase) SetA(a int)

SetA 设置 A

func (*OperatorBase) SetB

func (o *OperatorBase) SetB(b int)

SetB 设置 B

type OperatorFactory

type OperatorFactory interface {
	Create() Operator
}

OperatorFactory 是工厂接口

type Option

type Option func(msg *Message)

func WithAddress

func WithAddress(addr string) Option

func WithID

func WithID(id int) Option

func WithName

func WithName(name string) Option

func WithPhone

func WithPhone(phone int) Option

type PlusOperator

type PlusOperator struct {
	*OperatorBase
}

PlusOperator Operator 的实际加法实现

func (PlusOperator) Result

func (o PlusOperator) Result() int

Result 获取结果

type PlusOperatorFactory

type PlusOperatorFactory struct{}

PlusOperatorFactory 是 PlusOperator 的工厂类

func (PlusOperatorFactory) Create

func (PlusOperatorFactory) Create() Operator

type Singleton

type Singleton interface {
	// contains filtered or unexported methods
}

Singleton 是单例模式接口，导出的 通过该接口可以避免 GetInstance 返回一个包私有类型的指针

func GetInstance

func GetInstance() Singleton

GetInstance 用于获取单例模式对象
