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.
