Interface ResourceFinder

All Superinterfaces:
AutoCloseable, Iterator<String>
All Known Implementing Classes:
AbstractResourceFinderAdapter, CompositeResourceFinder, FilesScanner, JarFileScanner, PackageNamesScanner

public interface ResourceFinder extends Iterator<String>, AutoCloseable
An interface used for finding and opening (loading) new resources.

ResourceConfig will use all registered finders to obtain classes to be used as resource classes and/or providers. Method open() doesn't need to be called on all returned resource names, ResourceConfig can ignore some of them.

Currently, all resource names ending with ".class" will be accepted and processed (opened).

Extends AutoCloseable since version 2.19. The close() method is used to release allocated/opened resources (such as streams). When a resource finder is closed no other method should be invoked on it.
