Types

type RotateLog

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

func NewRotateLog

func NewRotateLog(logDir, fileTpl string) *RotateLog

*

• 获取 RotateLog 新实例 *
• @param logDir 日志存放目录, 带不带结尾的目录根号都行, 正反根号也都行
• @param fileTpl 文件名模板, 字符串中常量 DATA_PLACE_HOLE 为日期的位置, 会被替换成当前日期, 例如 runtime-_DATA_PLACE_HOLE_.log * *

func (*RotateLog) SetBackupDir

func (_l *RotateLog) SetBackupDir(backupDir string) *RotateLog

func (*RotateLog) Write

func (_l *RotateLog) Write(p []byte) (int, error)

type Runner

type Runner struct {
	Runnable bool
}

func NewRunner

func NewRunner() *Runner

func (*Runner) Exec

func (_this *Runner) Exec(runnerFunc RunnerFunc) *Runner

func (*Runner) Failed

func (_this *Runner) Failed(runnerFunc RunnerFinishFunc) *Runner

func (*Runner) IsRunnable

func (_this *Runner) IsRunnable() bool

func (*Runner) Success

func (_this *Runner) Success(runnerFunc RunnerFinishFunc) *Runner

type RunnerFinishFunc

type RunnerFinishFunc func()

type RunnerFunc

type RunnerFunc func() bool

type SpinLock

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

SpinLock implements a simple atomic spin lock, the zero value for a SpinLock is an unlocked spinlock.

func (*SpinLock) Lock

func (sl *SpinLock) Lock()

Lock locks sl. If the lock is already in use, the caller blocks until Unlock is called

func (*SpinLock) String

func (sl *SpinLock) String() string

func (*SpinLock) TryLock

func (sl *SpinLock) TryLock() bool

TryLock will try to lock sl and return whether it succeed or not without blocking.

func (*SpinLock) Unlock

func (sl *SpinLock) Unlock()

Unlock unlocks sl, unlike [Mutex.Unlock](http://golang.org/pkg/sync/#Mutex.Unlock), there's no harm calling it on an unlocked SpinLock
