Delegate CollectionFinder

public delegate IEnumerable<IResource> CollectionFinder(Uri collectionUri)

An CollectionFinder can be registered with the Processor; it is called in response to calls on the fn:collection() and fn:uri-collection() functions. When these functions are called, the delegate is called to get a collection of IResource objects representing resources identified by the supplied collection URI.

The implementation may be lazy: that is, the returned resource collection might not contain the actual resources, but only the information needed to fetch the resources when required. This means that any errors that occur when actually fetching the resources may be deferred.

Parameters:

collectionUri - The URI that will be used to identify the collection in calls on the fn:collection() and fn:uri-collection() functions. Should be an absolute URI.

Returns:

The set of resources represented by the collection URI
