Constructor Detail

EMFTag

protected EMFTag(int id,
                 int version)

Constructs a EMFTag.

Parameters:

id - id of the element

version - emf version in which this element was first supported

Method Detail

read

public org.freehep.util.io.Tag read(int tagID,
                                    org.freehep.util.io.TaggedInputStream input,
                                    int len)
                             throws java.io.IOException

Specified by:

read in class org.freehep.util.io.Tag

Throws:

java.io.IOException

read

public abstract EMFTag read(int tagID,
                            EMFInputStream emf,
                            int len)
                     throws java.io.IOException

Throws:

java.io.IOException

write

public void write(int tagID,
                  org.freehep.util.io.TaggedOutputStream output)
           throws java.io.IOException

Specified by:

write in class org.freehep.util.io.Tag

Throws:

java.io.IOException

write

public void write(int tagID,
                  EMFOutputStream emf)
           throws java.io.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:

java.io.IOException - thrown by EMFOutputStream

toString

public java.lang.String toString()

Specified by:

toString in class org.freehep.util.io.Tag

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

Parameters:

renderer - EMFRenderer storing the drawing session data
