      MulticastAnnouncement decodeMulticastAnnouncement(ByteBuffer buf, InvocationConstraints constraints) throws IOException
      Decodes the multicast announcement data contained in the given buffer in a manner that satisfies the specified absolute constraints, returning a MulticastAnnouncement instance that contains the decoded data. null constraints are considered equivalent to empty constraints. All the specified constraints are checked before this method returns.
      Parameters:
      buf - a buffer containing the packet data to decode. The multicast announcement data must begin at position zero of buf.
      constraints - the constraints to apply when decoding the data, or null
      Returns:
      the decoded multicast announcement data
      Throws:
      IOException - if an error occurs in interpreting the data
      UnsupportedConstraintException - if unable to satisfy the specified constraints
      SecurityException - if the given constraints cannot be satisfied due to insufficient caller permissions
      NullPointerException - if buf is null
