All Implemented Interfaces:

InputStreamSource, Resource

public class BitstreamResourceAccessByToken
extends BitstreamResource

This class acts as a AbstractResource used by Spring's framework to send the data in a proper and streamlined way inside the ResponseEntity body. This class' attributes are being used by Spring's framework in the overridden methods so that the proper attributes are given and used in the response. Unlike the BitstreamResource, this resource expects a valid and authorised access token to use when retrieving actual bitstream data. It will either set a special group in the temp context for READ of the bitstream, or turn off authorisation for the lifetime of the temp (autocloseable in try-with-resources) context
