Class AliasesInfo

java.lang.Object
org.bedework.calfacade.AliasesInfo
All Implemented Interfaces:
Serializable
public class AliasesInfo extends Object implements Serializable
Provide information about the aliases to a collection that can reference an href.

When we have a change to a resource we need to determine if that resource is visible via aliases to the containing collection

So if the containing collection is C and the resource has the name C/N it might be visible via the resource A which aliases C with the href A/N

The resource might not be visible if C or A are filtered or if dav access has restricted the rights.

Furthermore, we might have an alias A' to A, with a possibly different owner and different filtering.

This class is the result of querying the collections and aliases to determine that visibility. As this is a relatively expensive process we try to cache as much as possible. We can cache a copy that only contains entries for each collection and alias without reference to the entities. This can form the basis of an entity search. This cache needs to be flushed whenever there is a change to the system that affects any of these entries

We could also store the structure created when checking a given entity. This is flushed if the entity is deleted or - again - if the alias structure changes
