33 SVN::Delta wraps delta related function in subversion. The most
34 important one is SVN::Delta::Editor, the interface for describing tree
35 deltas. by default SVN::Delta::Editor relays method calls to its
36 internal member "_editor", which could either be an editor in C (such
37 as the one you get from get_commit_editor), or another
38 SVN::Delta::Editor object.
39
41 Driving Editors
42 If you want to drive a native editor (such as commit_editor obtained by
43 SVN::Repos::get_commit_editor), create a SVN::Delta::Editor object with
44 the native editor/baton pair. The object will then be ready to use and
45 its method calls will be relayed to the native editor.
46
47 Implementing Editors
48 If you want to implement an editor, subclass SVN::Delta::Editor and
49 implement the editors callbacks. see the METHODS section below.
50
51 CONSTRUCTOR - new (...)
52 new ($editor, $editor_baton)
53 Link to the native editor
54
55 You can also pass a hash array to new:
56
57 _debug
58 Turn on debug.
59
60 _editor
61 An arrayref of the editor/baton pair or another SVN::Delta::Editor
62 object to link with.
63
64 METHODS
65 Please consult the svn_delta.h section in the Subversion API. Member
66 functions of svn_delta_editor_t could be called as methods of
67 SVN::Delta::Editor objects, with the edit_baton omitted. The pool is
68 also optional.
69
70 If you are subclassing, the methods take exactly the same arguments as
71 the member functions (note that void ** are returned data though as
72 throughout the perl bindings), with the edit_baton omitted.
73
75 Functions returning editor/baton pair should really be typemapped to a
76 SVN::Delta::Editor object.
