Functions

func NewReader

func NewReader(meta *reader.Meta, conf conf.MapConf) (mr reader.Reader, err error)

Types

type ActiveReader

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

func NewActiveReader

func NewActiveReader(originPath, realPath, whence string, meta *reader.Meta, msgChan chan<- Result, errChan chan<- error) (ar *ActiveReader, err error)

func (*ActiveReader) Close

func (ar *ActiveReader) Close() error

func (*ActiveReader) Lag

func (ar *ActiveReader) Lag() (rl *LagInfo, err error)

func (*ActiveReader) Run

func (ar *ActiveReader) Run()

func (*ActiveReader) Status

func (ar *ActiveReader) Status() StatsInfo

func (*ActiveReader) SyncMeta

func (ar *ActiveReader) SyncMeta() string

除了sync自己的bufreader，还要sync一行linecache

type Reader

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

func (*Reader) Close

func (mr *Reader) Close() (err error)

func (*Reader) Expire

func (mr *Reader) Expire()

Expire 函数关闭过期的文件，再更新

func (*Reader) Lag

func (mr *Reader) Lag() (rl *LagInfo, err error)

func (*Reader) Name

func (mr *Reader) Name() string

func (*Reader) ReadLine

func (mr *Reader) ReadLine() (data string, err error)

func (*Reader) Reset

func (mr *Reader) Reset() (err error)

func (*Reader) SetMode

func (mr *Reader) SetMode(mode string, value interface{}) (err error)

func (*Reader) Source

func (mr *Reader) Source() string

func (*Reader) Start

func (mr *Reader) Start()

Start 仅调用一次，借用ReadLine启动，不能在new实例的时候启动，会有并发问题 处理StatIntervel以及Expire两大循环任务

func (*Reader) StatLogPath

func (mr *Reader) StatLogPath()

func (*Reader) Status

func (mr *Reader) Status() StatsInfo

func (*Reader) SyncMeta

func (mr *Reader) SyncMeta()

SyncMeta 从队列取数据时同步队列，作用在于保证数据不重复。

type Result

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