Class UndeletableAspect

java.lang.Object

org.alfresco.repo.node.UndeletableAspect

All Implemented Interfaces:

NodeServicePolicies.BeforeDeleteNodePolicy, ClassPolicy, Policy

public class UndeletableAspect
extends Object
implements NodeServicePolicies.BeforeDeleteNodePolicy

Undeletable aspect behaviour bean. Deletions of nodes with the ContentModel.ASPECT_UNDELETABLE are not allowed by default. This class registers the behaviour that prevents the deletion.

This aspect/behaviour combination allows for detailed application control of when node deletion is allowed or disallowed for particular nodes. It is not related to the normal permissions controls, which of course apply.

An example of its usage is in the SiteService, where SiteModel.TYPE_SITE nodes are given the ContentModel.ASPECT_UNDELETABLE as a mandatory aspect. Therefore any attempt to delete such a node will result in an exception. However, this behaviour is disabled within the SiteService in order to allow site node deletion from within that service but from no other code.

Since:

3.5.0
