Re[3]: object model to work with styles in PowerPoint

[Yegor Kozlov <ye...@dinom.ru>]

OK. The said makes sense.

I'm not sure about method signatures, need to think about it :).
Probably there will be
 getStyles();  //returns all applied styles
 and
 getStyles(int mask);  //returns specific styles

 getStyles( MASTER | TEXTRUN) is equivalent of getStyles()

We are going to add a bunch of methods to the TextRun object, probably
it's better to delegate calls to a special object :

TextFormat fmt = txrun.getTextFormat();
//do formatting via TextFormat

I was suggesting the idea, not the name. They almost certainly need to 
have a totally different name!

Hmm, I'd probably go with
  getStyles()
  getStylesAll()  - same as above
  getStylesTextRun()
  getStylesMaster()
but that's just me. If we do do the mask thing, we should have a "ALL" 
mask too

I'd be happy with that - we could also shift some of the logic from 
RichTextRun (for dealing with the actual StyleTextPropAtoms) there too
