This class represents a handle (a connection) to some resource, which may
be a class, native library, text file, image, etc. Handles are returned
by ResourceLoader's get methods.
Having the resource handle, in addition to accessing the resource data
(using methods getInputStream() or getBytes()) as well as
access resource metadata, such as attributes, certificates, etc.
As soon as the handle is no longer in use, it should be explicitly
close()d, similarly to I/O streams.
