CollectionFinder

All Known Implementing Classes:

StandardCollectionFinder

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface CollectionFinder
```
An instance of CollectionFinder can be registered with the Saxon configuration; it is called in response to calls on the fn:collection() and fn:uri-collection() functions. When these functions are called, the findCollection(XPathContext, String) method is called to get a ResourceCollection object representing the collection of resources identified by the supplied collection URI.

Since:

9.7: Supersedes CollectionURIResolver. The interface was changed to return Resource objects, to allow streamed processing of the documents in a collection; and to pass a properties object that can be used to indicate whether the collection is stable (that is, repeated requests return the same result)
