|
|
* Deletions of nodes with the {@link ContentModel#ASPECT_UNDELETABLE} are not allowed by default.
|
|
* This class registers the behaviour that prevents the deletion.
|
|
* <p/>
|
|
* 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.
|
|
* <p/>
|
|
* An example of its usage is in the {@link SiteService}, where {@link org.alfresco.repo.site.SiteModel#TYPE_SITE} nodes are given the
|
|
* {@link 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 {@link SiteService} in order to allow
|
|
* site node deletion from within that service but from no other code.
