Functions ¶
Types ¶
type Counter ¶
type Counter struct {
// contains filtered or unexported fields
}
Counter is a counting usage struct and provides functions to help couting.
func NewCounter ¶
NewCounter returns a Counter instance and the input num is the init number of the counter.
type MapFetcher ¶
type MapFetcher struct {
// contains filtered or unexported fields
}
MapFetcher is the wrapper for map[string]interface{}, and provides actions for easy usage of map actions.
func NewMapfetcher ¶
func NewMapfetcher(data map[string]interface{}) *MapFetcher
NewMapfetcher returns MapFetcher instance.
func (*MapFetcher) Add ¶
func (mf *MapFetcher) Add(key string, value interface{})
Add adds key value into map.
func (*MapFetcher) CopyMap ¶
func (mf *MapFetcher) CopyMap(from *MapFetcher)
CopyMap copies a MapFetcher's data map into self data map.
func (*MapFetcher) Err ¶
func (mf *MapFetcher) Err() error
Err returns MapFetcher holds err, it is using this article's thoughts: https://blog.golang.org/errors-are-values
func (*MapFetcher) Fetch ¶
func (mf *MapFetcher) Fetch(key string) interface{}
Fetch returns interface{} in the holding map by input key.
func (*MapFetcher) FetchBool ¶
func (mf *MapFetcher) FetchBool(key string) bool
FetchBool converts specific key value into boolean then returns.
func (*MapFetcher) FetchFloat ¶
func (mf *MapFetcher) FetchFloat(key string) float64
FetchFloat converts specific key value into float64 then returns.
func (*MapFetcher) FetchInt ¶
func (mf *MapFetcher) FetchInt(key string) int
FetchInt converts specific key value into int then returns.
func (*MapFetcher) FetchString ¶
func (mf *MapFetcher) FetchString(key string) string
FetchString converts specific key value into string then returns.
func (*MapFetcher) FetchTime ¶
func (mf *MapFetcher) FetchTime(key string) time.Time
FetchTime converts specific key value into time.Time then returns.
func (*MapFetcher) FetchTimeFromString ¶
func (mf *MapFetcher) FetchTimeFromString(key, location string) time.Time
FetchTimeFromString converts specific key value from string time into time.Time then returns.
func (*MapFetcher) GetMap ¶
func (mf *MapFetcher) GetMap() map[string]interface{}
GetMap returns whole map.
type ReturnForm ¶
ReturnForm is the kumay all server output form.
