Method Detail

read

public EMFTag read(int tagID,
                   EMFInputStream emf,
                   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

toString

public String toString()

Overrides:

toString in class EMFTag

Returns:

a description of the tagName and tagID
