public Resource createRelative(String relativePath) throws IOException
Create a resource relative to this resource.

 public boolean exists()
Return whether this resource actually exists in physical form.
This method performs a definitive existence check, whereas the
existence of a Resource handle only guarantees a
valid descriptor handle.

 public String getDescription()
Return a description for this resource,
to be used for error output when working with the resource.
Implementations are also encouraged to return this value
from their toString method.

 public File getFile() throws IOException
Return a File handle for this resource.

 public String getFilename()
Return a filename for this resource, i.e. typically the last
part of the path: for example, "myfile.txt".

 public URI getURI() throws IOException
Return a URI handle for this resource.

 public URL getURL() throws IOException
Return a URL handle for this resource.

 public boolean isOpen()
Return whether this resource represents a handle with an open
stream. If true, the InputStream cannot be read multiple times,
and must be read and closed to avoid resource leaks.
Will be false for typical resource descriptors.

 public boolean isReadable()
Return whether the contents of this resource can be read,
e.g. via #getInputStream()  or #getFile() .
Will be true for typical resource descriptors;
note that actual content reading may still fail when attempted.
However, a value of false is a definitive indication
that the resource content cannot be read.

 public long lastModified() throws IOException
Determine the last-modified timestamp for this resource.
