Interface ResourceResolver

All Superinterfaces:

AutoCloseable, CamelContextAware, HasCamelContext, Service, StaticService

public interface ResourceResolver
extends StaticService, CamelContextAware

SPI for resolving a Resource for a specific URI scheme.

Each resolver handles a single scheme (such as file, classpath, http) and turns a location into a Resource, or returns null if it cannot. The ResourceLoader dispatches to the matching resolver; scheme-specific resolvers are discovered from "META-INF/services/org/apache/camel/resource-resolver/", with an optional fallback used when no scheme matches.
