Yes, it is. Here's an example for embargo lifter. Setter is the same thing.
public void liftEmbargo(Context context, Item item) throws
SQLException, AuthorizeException, IOException {
...
Bundle[] bundles = item.getBundles("ORIGINAL");
if(bundles.length != 1) {
return;
}
Bundle originalBundle = bundles[0];
Bitstream[] bitstreams = originalBundle.getBitstreams();
for (int i = 0; i < bitstreams.length; i++) {
Bitstream bitstream = bitstreams[i];
ResourcePolicy policy = ResourcePolicy.create(context);
policy.setAction(Constants.READ);
policy.setEPerson(context.getCurrentUser());
policy.setGroup(Group.findByName(context, "mygroup"));
policy.setResource(bitstream);
policy.update();
}
...
}
But remember that metadata is per-item, not per-bitstream.
