示例1: writeSegmentsGen

/*
A utility for writing the SEGMENTS_GEN file to a Directory.

NOTE: this is an internal utility which is kept public so that it's
accessible by code from other packages. You should avoid calling this
method unless you're absolutely sure what you're doing!
*/
func writeSegmentsGen(dir store.Directory, generation int64) {
	if err := func() (err error) {
		var genOutput store.IndexOutput
		genOutput, err = dir.CreateOutput(INDEX_FILENAME_SEGMENTS_GEN, store.IO_CONTEXT_READONCE)
		if err != nil {
			return err
		}

		defer func() {
			err = mergeError(err, genOutput.Close())
			err = mergeError(err, dir.Sync([]string{INDEX_FILENAME_SEGMENTS_GEN}))
		}()

		if err = genOutput.WriteInt(FORMAT_SEGMENTS_GEN_CURRENT); err == nil {
			if err = genOutput.WriteLong(generation); err == nil {

					err = codec.WriteFooter(genOutput)
				}
			}
		}
		return err
	}(); err != nil {
		// It's OK if we fail to write this file since it's used only as
		// one of the retry fallbacks.
		dir.DeleteFile(INDEX_FILENAME_SEGMENTS_GEN)
		// Ignore error; this file is only used in a retry fallback on init
	}
