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.
