Functions

func HeadPatternMode 

func HeadPatternMode(mode string, v interface{}) (reg *regexp.Regexp, err error)

Types

type ActiveReader 

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

func NewActiveReader 

func NewActiveReader(logPath, whence string, meta *Meta, msgChan chan<- Result) (ar *ActiveReader, err error)

func (*ActiveReader) Close 

func (ar *ActiveReader) Close() error

func (*ActiveReader) Run 

func (ar *ActiveReader) Run()

func (*ActiveReader) Status added in v1.3.1 

func (ar *ActiveReader) Status() utils.StatsInfo

func (*ActiveReader) SyncMeta 

func (ar *ActiveReader) SyncMeta() string

type BufReader 

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

BufReader implements buffering for an FileReader object.

func NewReaderSize 

func NewReaderSize(rd FileReader, meta *Meta, size int) (*BufReader, error)

NewReaderSize returns a new Reader whose buffer has at least the specified size. If the argument FileReader is already a Reader with large enough size, it returns the underlying Reader.

func (*BufReader) Close 

func (b *BufReader) Close() error

func (*BufReader) Name 

func (b *BufReader) Name() string

func (*BufReader) ReadLine

func (*BufReader) ReadString 

func (b *BufReader) ReadString(delim byte) (ret string, err error)

ReadString reads until the first occurrence of delim in the input, returning a string containing the data up to and including the delimiter. If ReadString encounters an error before finding a delimiter, it returns the data read before the error and the error itself (often io.EOF). ReadString returns err != nil if and only if the returned data does not end in delim. For simple uses, a Scanner may be more convenient.
