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.
