go特性学习

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")

}
