The VersionableEditor provides two possible ways to handle versionable nodes:

after - the added child node

Returns:

an editor for processing the subtree below the added node, or null if the subtree does not need processing

Throws:

CommitFailedException - if processing failed

childNodeChanged

public Editor childNodeChanged(String name,
 NodeState before,
 NodeState after)
                        throws CommitFailedException

Description copied from interface: Editor

Processes a changed child node. This method gets called for all child nodes that may contain changes between the before and after states.

Specified by:

childNodeChanged in interface Editor

Overrides:

childNodeChanged in class DefaultEditor

Parameters:

name - name of the changed node

before - child node before the change

after - child node after the change

Returns:

an editor for processing the subtree below the added node, or null if the subtree does not need processing

Throws:

CommitFailedException - if processing failed

childNodeDeleted

public Editor childNodeDeleted(String name,
 NodeState before)
                        throws CommitFailedException

leave

public void leave(NodeState before,
 NodeState after)
           throws CommitFailedException

Description copied from interface: Editor

Called after the given before and after states are compared. The implementation can use this method to post-process information collected during the content diff. For example an implementation that during the diff just recorded the fact that this node was modified in some way could then use this method to trigger an index update based on that modification flag.

Specified by:

leave in interface Editor

leave in class DefaultEditor

Parameters:

before - before state, non-existent if this node was added

after - after state, non-existent if this node was removed
