Member Function Documentation

virtual void IlvGraphOutputFile::writeObject ( const IlvGraphic *  obj )

virtual

Writes an object in the output stream.

Adds information specific to each object before its description block. This information includes the layer index as well as the type of the object (node, link, or other type of object). The method is automatically called by the IlvManagerOutputFile::saveAll() method and is not to be called directly by the programmer.

Parameters

obj	The object to write.

Reimplemented from IlvManagerOutputFile.
