NAME
       SVN::Delta - Subversion delta functions

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

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

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

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

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

           # implement an editor in perl
           SVN::Repos::dirdelta($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 getcommiteditor), or another
       SVN::Delta::Editor object.

       If you want to drive a native editor (such as commiteditor obtained by
       SVN::Repos::getcommiteditor), 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.

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

       new ($editor, $editorbaton)
           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.

       MMEETTHHOODDSS

       Please consult the svndelta.h section in the Subversion API. Member
       functions of svndeltaeditort could be called as methods of
       SVN::Delta::Editor objects, with the editbaton 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 editbaton omitted.

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