NAME
       SVN::Delta - Subversion delta functions

SYNOPSIS
           require SVN::Core;
           require SVN::Repos;
           require SVN::Delta;

           # driving an editor
           my $editor = SVN::Delta::Editor->
               new(SVN::Repos::get_commit_editor($repos, "file://$repospath",
                                                 '/', 'root', 'FOO', \&committed));

           my $rootbaton = $editor->open_root(0);

           my $fbaton = $editor->add_file('filea', $rootbaton,
                                          undef, -1);

           my $ret = $editor->apply_textdelta($fbaton, undef);
           SVN::TxDelta::send_string("FILEA CONTENT", @$ret);

           # implement an editor in perl
           SVN::Repos::dir_delta($root1, $path, undef,
                                 $root2, $path,
                                 SVN::Delta::Editor->new(_debug=>1),
                                 1, 1, 0, 1

DESCRIPTION
       SVN::Delta wraps delta related function in subversion. The most
       important one is SVN::Delta::Editor, the interface for describing tree
       deltas. by default SVN::Delta::Editor relays method calls to its
       internal member "_editor", which could either be an editor in C (such
       as the one you get from get_commit_editor), or another
       SVN::Delta::Editor object.

SVN::Delta::Editor
   Driving Editors
       If you want to drive a native editor (such as commit_editor obtained by
       SVN::Repos::get_commit_editor), create a SVN::Delta::Editor object with
       the native editor/baton pair. The object will then be ready to use and
       its method calls will be relayed to the native editor.

   Implementing Editors
       If you want to implement an editor, subclass SVN::Delta::Editor and
       implement the editors callbacks. see the METHODS section below.

   CONSTRUCTOR - new(...)
       new($editor, $editor_baton)
           Link to the native editor

       You can also pass a hash array to new:

       _debug
           Turn on debug.

       _editor
           An arrayref of the editor/baton pair or another SVN::Delta::Editor
           object to link with.

   METHODS
       Please consult the svn_delta.h section in the Subversion API. Member
       functions of svn_delta_editor_t could be called as methods of
       SVN::Delta::Editor objects, with the edit_baton omitted. The pool is
       also optional.

       If you are subclassing, the methods take exactly the same arguments as
       the member functions (note that void ** are returned data though as
       throughout the perl bindings), with the edit_baton omitted.

BUGS
       Functions returning editor/baton pair should really be typemapped to a
       SVN::Delta::Editor object.
