而后我写了一些测试代码：
dept1 :=
Dept{
name: "MySohu",
building: "Internet",
floor: 7}
switch v := interface{}(dept1).(type) {
case DeptModeFull:
fmt.Printf("The dept1 is a DeptModeFull.\n")
case DeptModeB:
fmt.Printf("The dept1 is a DeptModeB.\n")
case DeptModeA:
fmt.Printf("The dept1 is a DeptModeA.\n")
default:
fmt.Printf("The type of dept1 is %v\n", v)
}
deptPtr1 := &dept1
if _, ok := interface{}(deptPtr1).(DeptModeFull); ok {
fmt.Printf("The deptPtr1 is a DeptModeFull.\n")
}
if _, ok := interface{}(deptPtr1).(DeptModeA); ok {
fmt.Printf("The deptPtr1 is a DeptModeA.\n")
}
if _, ok := interface{}(deptPtr1).(DeptModeB); ok {
fmt.Printf("The deptPtr1 is a DeptModeB.\n")
}
