Description copied from class: Tag

This writes the information to the given output

Specified by:

Throws:

IOException

write

public void write(int tagID,
                  EMFOutputStream emf)
           throws IOException

Writes the extra tag information to the outputstream in binary format. This implementation writes nothing, but concrete tags may override this method. This method is called just after the TagHeader is written.

Parameters:

tagID - id of the tag

emf - Binary CGM output stream

Throws:

IOException

toString

public String toString()

Specified by:

toString in class Tag

Returns:

a description of the tagName and tagID
