- All Implemented Interfaces:
- DataOutput, FinishableOutputStream, TaggedOutput
- Direct Known Subclasses:
- CGMOutputStream, EMFOutputStream, SWFOutputStream
- 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.
