type Timer 

type Timer struct {
	// contains filtered or unexported fields
}

Timer can be used for retransmission, it will manage retry times automatically

func NewTimer 

func NewTimer(d time.Duration, maxRetryTimes int32, expiredFunc func(expireTimes int32), cancelFunc func()) *Timer

NewTimer will return a Timer struct and create a goroutine. Then it calls expiredFunc every time interval d until the user call Stop(). the number of expire event is be recorded when the timer is active. When the number of expire event is > maxRetryTimes, then the timer will call cancelFunc and turns off itself. Whether expiredFunc pass a parameter expireTimes to tell the user that the current expireTimes.

func (*Timer) ExpireTimes 

func (t *Timer) ExpireTimes() int32

ExpireTimes return the current expire times of the timer

func (*Timer) MaxRetryTimes 

func (t *Timer) MaxRetryTimes() int32

MaxRetryTimes return the max retry times of the timer

func (*Timer) Stop 

func (t *Timer) Stop()

Stop turns off the timer, after Stop, no more timeout event will be triggered. User should call Stop() only once otherwise it may hang on writing to done channel

type TimerValue 

type TimerValue struct {
	Enable        bool
	ExpireTime    time.Duration
	MaxRetryTimes int32
}

type UERadioCapabilityForPaging 

type UERadioCapabilityForPaging struct {
