func (*DirCache) FindDir ¶

func (dc *DirCache) FindDir(path string, create bool) (pathID string, err error)

FindDir finds the directory passed in returning the directory ID starting from pathID

Path shouldn't start or end with a /

If create is set it will make the directory if not found ¶

Algorithm:

Look in the cache for the path, if found return the pathID
If not found strip the last path off the path and recurse
Now have a parent directory id, so look in the parent for self and return it

func (*DirCache) FindPath ¶

func (dc *DirCache) FindPath(path string, create bool) (leaf, directoryID string, err error)

FindPath finds the leaf and directoryID from a path

Do not call FindPath with the root directory - it will return an error ¶

If create is set parent directories will be created if they don't exist

func (*DirCache) FindRoot ¶

func (dc *DirCache) FindRoot(create bool) error

FindRoot finds the root directory if not already found

Resets the root directory ¶

If create is set it will make the directory if not found

func (*DirCache) FindRootAndPath ¶

func (dc *DirCache) FindRootAndPath(path string, create bool) (leaf, directoryID string, err error)

FindRootAndPath finds the root first if not found then finds leaf and directoryID from a path

If create is set parent directories will be created if they don't exist

func (*DirCache) Flush ¶

func (dc *DirCache) Flush()

Flush the map of all data

func (*DirCache) FlushDir ¶

func (dc *DirCache) FlushDir(dir string)

FlushDir flushes the map of all data starting with dir

If dir is empty then this is equivalent to calling ResetRoot

func (*DirCache) FoundRoot ¶

func (dc *DirCache) FoundRoot() bool

FoundRoot returns whether the root directory has been found yet

Call this from FindLeaf or CreateDir only

func (*DirCache) Get ¶

func (dc *DirCache) Get(path string) (id string, ok bool)

Get an ID given a path

func (*DirCache) GetInv ¶

func (dc *DirCache) GetInv(id string) (path string, ok bool)

GetInv gets a path given an ID

func (*DirCache) Put ¶

func (dc *DirCache) Put(path, id string)

Put a path, id into the map

func (*DirCache) ResetRoot ¶

func (dc *DirCache) ResetRoot()

ResetRoot resets the root directory to the absolute root and clears the DirCache

func (*DirCache) RootID ¶

func (dc *DirCache) RootID() string

RootID returns the ID of the root directory

This should be called after FindRoot

func (*DirCache) RootParentID ¶

func (dc *DirCache) RootParentID() (string, error)

RootParentID returns the ID of the parent of the root directory

This should be called after FindRoot
