示例1: printVal
// printVal prints the given value corresponding to the given data type.
// The value is already checked for the compatibility with the data type.
func printVal(t design.DataType, val interface{}) string {
switch {
case t.IsPrimitive():
// For primitive types, simply print the value
s := fmt.Sprintf("%#v", val)
if t == design.DateTime {
s = fmt.Sprintf("time.Parse(time.RFC3339, %s)", s)
}
return s
case t.IsHash():
// The input is a hash
h := t.ToHash()
hval := val.(map[interface{}]interface{})
if len(hval) == 0 {
return fmt.Sprintf("%s{}", GoTypeName(t, nil, 0, false))
}
var buffer bytes.Buffer
buffer.WriteString(fmt.Sprintf("%s{", GoTypeName(t, nil, 0, false)))
for k, v := range hval {
buffer.WriteString(fmt.Sprintf("%s: %s, ", printVal(h.KeyType.Type, k), printVal(h.ElemType.Type, v)))
}
buffer.Truncate(buffer.Len() - 2) // remove ", "
buffer.WriteString("}")
return buffer.String()
case t.IsArray():
// Input is an array
a := t.ToArray()
aval := val.([]interface{})
if len(aval) == 0 {
return fmt.Sprintf("%s{}", GoTypeName(t, nil, 0, false))
}
var buffer bytes.Buffer

default:
// shouldn't happen as the value's compatibility is already checked.
