Instance Method Details

#bitstream_for(resource) ⇒ Bitstream

Gets the bitstream for the specified resource. (Note that this does no validation; if the resource is not in the manifest, or the corresponding entry is not in the ZIP file, the behavior of the returned Bitstream is undefined.)

Returns:

  • (Bitstream) —

    a bitstream wrapping the ZIP entry for the specified resource.
