Subject [jira] Commented: (JCR-2687) [PATCH] DeepNodeCreator utility
Date Thu, 12 Aug 2010 09:48:15 GMT

    [ https://issues.apache.org/jira/browse/JCR-2687?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12897657#action_12897657

Jukka Zitting commented on JCR-2687:

Agreed, composition over inheritance. This approach will also make it more convenient to provide
useful constants for common cases like when all the created types should be nt:unstructured
or nt:folder.

Instead of the separate getNodeType and nodeCreated parts, I'd use a more generic strategy
interface like this:

    interface ChildNodeCreator {
        Node addChildNode(Node parent, String name)
            throws RepositoryException;

This would allow more complete customization of the child node creation part. We could provide
default implementations in constants like ChildNodeCreator.DEFAULT (that just does parent.addNode(name))
and .UNSTRUCTURED or .FOLDER (that set the specific type) as well as in factory methods like
.withType(String primary, String... mixins) that allows a custom node type and any number
of mixins to be specified for the child nodes.
