func (*Model) CurrentLocalVersion

func (m *Model) CurrentLocalVersion(folder string) (int64, bool)

func (*Model) DelayScan

func (m *Model) DelayScan(folder string, next time.Duration)

func (*Model) DeviceStatistics

func (m *Model) DeviceStatistics() map[string]stats.DeviceStatistics

func (m *Model) GetIgnores(folder string) ([]string, []string, error)

func (*Model) GlobalDirectoryTree

func (m *Model) GlobalDirectoryTree(folder, prefix string, levels int, dirsonly bool) map[string]interface{}

func (*Model) GlobalSize

func (m *Model) GlobalSize(folder string) (nfiles, deleted int, bytes int64)

GlobalSize returns the number of files, deleted files and total bytes for all files in the global model.

func (*Model) Index

func (m *Model) Index(deviceID protocol.DeviceID, folder string, fs []protocol.FileInfo, flags uint32, options []protocol.Option)

Index is called when a new device is connected and we receive their full index. Implements the protocol.Model interface.

func (*Model) IndexUpdate

func (m *Model) IndexUpdate(deviceID protocol.DeviceID, folder string, fs []protocol.FileInfo, flags uint32, options []protocol.Option)

IndexUpdate is called for incremental updates to connected devices' indexes. Implements the protocol.Model interface.
