//     Function: TypedWritable::mark_bam_modified

//  Description: Increments the bam_modified counter, so that this
//               object will be invalidated and retransmitted on any
//               open bam streams.  This should normally not need to
//               be called by user code; it should be called
//               internally when the object has been changed in a way
//               that legitimately requires its retransmission to any
//               connected clients.

//     Function: TypedWritable::get_bam_modified
//       Access: Public
//  Description: Returns the current bam_modified counter.  This

//               whenever the object is modified.

//     Function: TypedWritable::encode_to_bam_stream
//       Access: Published
//  Description: Converts the TypedWritable object into a single
//               stream of data using a BamWriter, and returns that
//               data as a string string.  Returns empty string on
//               failure.
//
//               This is a convenience method particularly useful for
//               cases when you are only serializing a single object.
//               If you have many objects to process, it is more
//               efficient to use the same BamWriter to serialize all
//               of them together.
