Golang之泛型程式設計-細節

Golang沒有泛型<>，但是可以通過interface{}來接收各種類型值。

如下運用切片和泛型執行個體：

type Slice []interface{}func NewSlice() Slice {    return make(Slice, 0)}func (this* Slice) Add(elem interface{}) error {    for _, v := range *this {        if v == elem {            fmt.Printf("Slice:Add elem: %v already exist\n", elem)            return ERR_ELEM_EXIST        }    }    *this = append(*this, elem)    fmt.Printf("Slice:Add elem: %v succ\n", elem)    return nil}func (this* Slice) Remove(elem interface{}) error {    found := false    for i, v := range *this {        if v == elem {            if i == len(*this) - 1 {                *this = (*this)[:i]            } else {                *this = append((*this)[:i], (*this)[i+1:]...)            }            found = true            break        }    }    if !found {        fmt.Printf("Slice:Remove elem: %v not exist\n", elem)        return ERR_ELEM_NT_EXIST    }    fmt.Printf("Slice:Remove elem: %v succ\n", elem)    return nil}
