func (*Extractor) Close

func (e *Extractor) Close() error

Close fd

func (*Extractor) DecodeFileName

func (e *Extractor) DecodeFileName(header zip.FileHeader) string

DecodeFileName decode filename

func (*Extractor) Extract

type Resetter

type Resetter interface {
	// Reset discards any buffered data and resets the Resetter as if it was
	// newly initialized with the given reader.
	Reset(r io.Reader) error
}

Resetter resets a ReadCloser returned by NewReader or NewReaderDict to switch to a new underlying Reader. This permits reusing a ReadCloser instead of allocating a new one.
