}

func NewModel 

func NewModel(cfg *config.Wrapper, id protocol.DeviceID, deviceName, clientName, clientVersion string, ldb *leveldb.DB) *Model

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.

func (*Model) LocalSize 

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

LocalSize returns the number of files, deleted files and total bytes for all files in the local folder.

func (*Model) NeedFolderFiles added in v0.10.15 

func (m *Model) NeedFolderFiles(folder string, page, perpage int) ([]db.FileInfoTruncated, []db.FileInfoTruncated, []db.FileInfoTruncated, int)

NeedFolderFiles returns paginated list of currently needed files in progress, queued, and to be queued on next puller iteration, as well as the total number of files currently needed.

func (*Model) NeedSize 

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

NeedSize returns the number and total size of currently needed files.
