public abstract class TaggedOutputStream
extends ByteCountOutputStream
implements TaggedOutput

Class to write Tagged blocks to a Stream. The tagged blocks (Tags) contain a tagID and a Length, so that known and unknown tags (read with the TaggedInputStream) can again be written. The stream also allows to write Actions, which again come with a actionCode and a length. A concrete implementation of this stream should encode/write the TagHeader. All Concrete tags should be inherited from the Tag class and implement their write methods.
