Golang没有泛型<>，但是可以通过interface{}来接收各种类型值。
如下运用切片和泛型实例：
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
}
