A WorkingTree represents the editable working copy of a branch.
20
20
Operations which represent the WorkingTree are also done here,
21
such as renaming or adding files. The WorkingTree has an inventory
22
which is updated by these operations. A commit produces a
23
new revision based on the workingtree and its inventory.
21
such as renaming or adding files.
25
23
At the moment every WorkingTree has its own branch. Remote
26
24
WorkingTrees aren't supported.
28
To get a WorkingTree, call bzrdir.open_workingtree() or
26
To get a WorkingTree, call controldir.open_workingtree() or
29
27
WorkingTree.open(dir).
