public class FileResource
extends URLResource

File Resource. Handle resources of implied or explicit file type. This class can check for aliasing in the filesystem (eg case insensitivity). By default this is turned on, or it can be controlled by calling the static method @see FileResource#setCheckAliases(boolean)
