Class DelegatingResourceLoader

java.lang.Object

org.springframework.cloud.deployer.resource.support.DelegatingResourceLoader

All Implemented Interfaces:

org.springframework.beans.factory.Aware, org.springframework.context.ResourceLoaderAware, org.springframework.core.io.ResourceLoader

public class DelegatingResourceLoader
extends Object
implements org.springframework.core.io.ResourceLoader, org.springframework.context.ResourceLoaderAware

A ResourceLoader implementation that delegates to other ResourceLoader instances that are stored in a Map with their associated URI schemes as the keys. If a scheme does not exist within the Map, it will fallback to a DefaultResourceLoader. The Map may be empty (or null).

This implementation is also caching remote resources which are not directly accessible as File into either a given cache directory or on default a temporary location prefixed by "deployer-resource-cache".
