          int len)
            throws IOException

Specified by:

read in class EMFTag

Throws:

IOException

write

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

Description copied from class: EMFTag

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.

Overrides:

write in class EMFTag

Parameters:

tagID - id of the tag

emf - Binary CGM output stream

Throws:

IOException - thrown by EMFOutputStream

toString

public String toString()

Overrides:

toString in class EMFTag

Returns:

a description of the tagName and tagID

render

public void render(EMFRenderer renderer)

displays the tag using the renderer

Specified by:

render in interface GDIObject

Overrides:

render in class EMFTag

Parameters:

renderer - EMFRenderer storing the drawing session data
