public interface ASN1BitStringParser extends ASN1Encodable, InMemoryRepresentable
A basic parser for a BIT STRING object

  • Method Details

    • getBitStream

      InputStream getBitStream() throws IOException
      Return an InputStream representing the contents of the BIT STRING. The final byte, if any, may include pad bits. See getPadBits().
      Returns:
      an InputStream with its source as the BIT STRING content.
      Throws:
      IOException

    • getOctetStream

      InputStream getOctetStream() throws IOException
      Return an InputStream representing the contents of the BIT STRING, where the content is expected to be octet-aligned (this will be automatically checked during parsing).
      Returns:
      an InputStream with its source as the BIT STRING content.
      Throws:
      IOException

    • getPadBits

      int getPadBits()
      Return the number of pad bits, if any, in the final byte, if any, read from getBitStream(). This number is in the range zero to seven. That number of the least significant bits of the final byte, if any, are not part of the contents and should be ignored. NOTE: Must be called AFTER the stream has been fully processed. (Does not need to be called if getOctetStream() was used instead of getBitStream()).
      Returns:
      the number of pad bits. In the range zero to seven.
