Types

type AroundFunc

type AroundFunc func(pctx ProxyContext, method reflect.Value, args []reflect.Value) []reflect.Value

func (AroundFunc) Around

func (around AroundFunc) Around(pctx ProxyContext, method reflect.Value, args []reflect.Value) []reflect.Value

type Arounder

type Arounder interface {
	Around(pctx ProxyContext, method reflect.Value, args []reflect.Value) []reflect.Value
}

type ArounderMap

type ArounderMap map[ProxyContext]AroundFunc

func (ArounderMap) Merge

func (m ArounderMap) Merge(nm ArounderMap) (mr ArounderMap)

type CtxFunc

type CtxFunc func(ctx ProxyContext, method any, args []any) (res []any)

CtxFunc 对于method: func(string, int) (int, error) f := method.(func(string, int) (int, error)) a1 := args[0].(string) a2 := args[1].(int) r1, r2 := f(a1, a2) res = append(res, r1, r2)

type IAroundFunc

type IAroundFunc interface {
	Around(pctx ProxyContext, method reflect.Value, args []reflect.Value) []reflect.Value
}

type IIoc

type IIoc interface {
	Inject(v any) (err error)
	RegisterProvider(v any) (err error)
}

type IProxyContext

type IProxyContext interface {
	LogShortf(format string, args ...any)
	Logf(format string, args ...any)
	String() string
}

type Ioc

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

Ioc 控制反转，Inversion of Control

func NewIoc

func NewIoc(
	enableUnexportedFieldSetValue bool,
) *Ioc

func (*Ioc) Inject

func (ioc *Ioc) Inject(v any) (err error)

Inject 注入依赖，传入结构体，根据结构体的字段类型找到对应的provider，执行后将获得的值赋予字段

遍历v的字段，找到字段类型，再根据字段类型找到provider，调用provider获得实例，再把实例值赋给该字段 provider需要在接口定义处注册，注册到一个统一管理的地方 如果provider需要参数，则根据参数类型继续找寻相应的provider，直至初始化完成

func (*Ioc) RegisterProvider

func (ioc *Ioc) RegisterProvider(v any) (err error)

RegisterProvider 注册provider函数，形如`func New(fielda TypeA, fieldb TypeB) (T)`

type IproxyImpl

type IproxyImpl interface {
	Around(provider any, mock any, arounder Arounder) any
}

type Proxy

type Proxy interface {
	Around(provider any, mock any, arounder Arounder) any
}

Proxy 在层间依赖调用时插入钩子调用，类似AOP

func NewProxy

func NewProxy() Proxy

type ProxyContext

type ProxyContext struct {
	PkgPath       string
	InterfaceName string // TODO: 接口或结构体的名字，不为空时表示方法，为空时表示函数
	MethodName    string
}

每个包、每个接口、每个方法唯一对应一个方法

func (ProxyContext) LogShortf

func (pctx ProxyContext) LogShortf(format string, args ...any)

func (ProxyContext) Logf

func (pctx ProxyContext) Logf(format string, args ...any)

func (ProxyContext) String

func (pctx ProxyContext) String() string

func (ProxyContext) Uniq

func (pctx ProxyContext) Uniq() string
