func (*CacheDir) CheckFileIntegrity ¶

func (self *CacheDir) CheckFileIntegrity(name string) (ok bool, fullpath string, err error)

func (*CacheDir) ComparisonFunction ¶

func (self *CacheDir) ComparisonFunction(f1, f2 os.FileInfo) (int, error)

func (*CacheDir) Delete ¶

func (self *CacheDir) Delete(name string)

func (*CacheDir) Disable ¶

func (self *CacheDir) Disable(name string)

func (*CacheDir) EnsureDirectory ¶

func (self *CacheDir) EnsureDirectory(
	try_create_dir bool,
	try_write_file bool,
) error

Ensure directory acceptable to be used for file storage

func (*CacheDir) GenNames ¶

func (self *CacheDir) GenNames(oname string) (name, name_disabled, name_sum, name_sum_disabled string)

TODO: probaby, this function requires optimization oname must be suffixed with WorkExtension. it will be suffized automatically, if it's not

func (*CacheDir) Get ¶

func (self *CacheDir) Get() (name string, data io.ReadCloser, err error)

Get() locks file with returned name, so Get() can be called asyncronously and Get() will not return locked files. files can be unlocked with Unlock(), Disable() or Delete() functions

func (*CacheDir) HaveCache ¶

func (self *CacheDir) HaveCache() (bool, error)

func (*CacheDir) JoinFileName ¶

func (self *CacheDir) JoinFileName(filename string) string

preforms filepath joining of directory path and provided filename

func (*CacheDir) NextFile ¶

func (self *CacheDir) NextFile() (name string, err error)

err = os.ErrNotExist if no any file found. acceptable filenames should be already checked by self.WorkingFiles() so NextFile() only find's the oldest one and treats any errors as not acceptable

func (*CacheDir) ParseWorkFileName ¶

func (self *CacheDir) ParseWorkFileName(n string) (t time.Time, err error)

func (*CacheDir) ParseWorkFileNameByFileInfo ¶

func (self *CacheDir) ParseWorkFileNameByFileInfo(fi os.FileInfo) (t time.Time, err error)

func (*CacheDir) Put ¶

func (self *CacheDir) Put(data io.Reader) (err error)

func (*CacheDir) UnlockFile ¶

func (self *CacheDir) UnlockFile(name string)

func (*CacheDir) WorkingFiles ¶

func (self *CacheDir) WorkingFiles() (ret []os.FileInfo, err error)
