[Dxfreader-info] DXFReader with delegates?

[Michael C. <mic...@gm...>]

Hey list,

thought it might be cool to add delegates to the DXFReader Model  
class. I think that if one wanted to add multi-threading to the  
loader, it would be easier that way. The reader could continue  
reading, calling delegates as it hits things like entities, header  
sections, etc. If the delegate chose to, it could kick off a thread to  
do it's processing on that element. The element would still be added  
to the model for later if so desired, but the processor would have a  
chance to create, say a DK drawing layer and render the element on it,  
while the reader is busy reading. I don't know if it would be all that  
much of a performance gain though and I'd probably want to do some  
profiling before adding it in there, but it's an idea.

It's kind of a cross between what a SAX and DOM parser is to XML. One  
is streaming using callbacks, and the other is model-based. Best of  
both worlds.

Michael
