type Class ¶

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

func NewClass() *Class

func (task Class) GetDerived() Classer

func (task Class) GetDerivedElse(defaultClass Classer) Classer

func (task *Class) SetDerived(derived Classer)

type Classer ¶

type Classer interface {
	GetDerived() Classer
	GetDerivedElse(defaultClass Classer) Classer
	SetDerived(derived Classer)
}

Classer is an interface to enhance go's embed struct with virtual member function in C++|Java It's used like this: import "github.com/searKing/golang/go/util/class"

type Pet struct {
	class.Class
}

func (pet *Pet) Name() string {
	return "pet"
}

func (pet *Pet) VirtualUpperName() string {
	p := pet.GetDerivedElse(pet).(Peter)
	return strings.ToUpper(p.Name())
}

func (pet *Pet) UpperName() string {
	return strings.ToUpper(pet.Name())
}

//Dog derived from Pet

type Dog struct {
	Pet
}

func NewDogEmbedded() *Dog {
	return &Dog{}
}

func NewDogDerived() *Dog {
	dog := &Dog{}
	dog.SetDerived(dog)
	return dog
}

func (dog *Dog) Name() string {
	return "dog"
}
