All Implemented Interfaces:

ISVNDeltaConsumer, ISVNEditor

public class SVNReplicationEditor
extends java.lang.Object
implements ISVNEditor

The SVNReplicationEditor is an editor implementation used by a repository replicator as a bridge between an update editor for the source repository and a commit editor of the target one. This editor is provided to an update method of a source SVNRepository driver to properly translate the calls of that driver to calls to a commit editor of the destination SVNRepository driver.
