An InventoryEntry has the following fields, which are also
40
48
present in the XML inventory-entry element:
43
* *name*: (only the basename within the directory, must not
45
* *kind*: "directory" or "file"
46
* *directory_id*: (if absent/null means the branch root directory)
47
* *text_sha1*: only for files
48
* *text_size*: in bytes, only for files
49
* *text_id*: identifier for the text version, only for files
51
InventoryEntries can also exist inside a WorkingTree
52
inventory, in which case they are not yet bound to a
53
particular revision of the file. In that case the text_sha1,
54
text_size and text_id are absent.
53
(within the parent directory)
59
file_id of the parent directory, or ROOT_ID
62
the revision_id in which the name or parent of this file was
66
sha-1 of the text of the file
69
size in bytes of the text of the file
72
the revision_id in which the text of this file was introduced
74
(reading a version 4 tree created a text_id field.)
