Newb question

Let me first say that I am not directly using KNIME but I had a friend come to me with a question that I could not directly and easily solve so here I am.  

 

Her quesiton is...

 

"We need to use some of the base code in order to modify how it treats the individual nodes.

Thats why just the node source code isn't what's needed (though it is helpful additionally)."
 
But she says she is having difficulty finding all of the source code and not just individual node code.    Is there any information I could relay to her in that regard?
 
Any help will be appriciated on her end, I'm sure!   I'm just the middleman...
 

If you download the KNIME SDK you will have all sources from the standard packages available, if you need additional sources from other extensions make sure you install the corresponding sources from our update site, too.
