Abstract

This PEG is close to PEG nodeview_abstract--mudyc where I did suggest simple method to place a node without any information about the content of a node. Now, in this PEG, I've a new solution for the problem that we still don't know a way to handle placing part of the job.

Issues

None

Design

NodeView, which is responsible to place a node, must get information of the content of the node. Space/FFC provides this information with method getEnfilade. Once we have enfilade we can split it smaller ones so that TextSpan, ImageSpan and PageSpan etc. are in their own enfilades. Now we can give the pieces of content to correct handler(text,image and page etc.) where it is placed in a vob and putted in the vobscene.

Changes

We need a new interface for different content handlers:

public interface ContentHandler {
    void place(VobScene vs, int box, Enfilade enf);
    void getSize(Enfilade enf, float[] size);        
}

Now we go back to nodeview_abstract--mudyc PEG and get the missing pieces from there:

public abstract class TextHandler implements ContentHandler, TextState, TextContext{
    
   // implement...

}

public abstract class PageHandler implements ContentHandler, PageState, PageContext {

   // implement...

}

etc...
