Class StaticResourceServlet.LocalResource

java.lang.Object

de.businesscode.bcdui.web.servlets.StaticResourceServlet.LocalResource

All Implemented Interfaces:

StaticResourceServlet.Resource

Enclosing class:

StaticResourceServlet

public static class StaticResourceServlet.LocalResource
extends Object
implements StaticResourceServlet.Resource

This class represents one single resource which is either a file on the file system or a URL from the classpath. Please note that a resource which could not be located results is also represented by a Resource object, but the notFound() method will return true. This is useful, because a not-found resource has also a lookup path so the getPath() method works also in this case.
