inputStream

InputStream inputStream()
                        throws ResourceException

Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.

Returns:

just opened InputStream

Throws:

ResourceException - is the file does not exists or if the resource is a directory

openChannel

Channel openChannel(ModeFlags flags,
                  int perm)
                    throws ResourceException

Throws:
