Retrieving any FO object knowing its ID inside the Layout Manager

[Jan Tosovsky <j....@email.cz>]

Dear All,

when constructing the content in the Layout Manager, I can access properties
of the processed FO object, but I'd like to access properties of an
arbitrary FO object knowing its ID.

Inside the Layout Manager I can only retrieve the PageViewport for the
specific ID, but this object doesn't tell much about the FO object itself.
PageViewport pageViewport = getPSLM().getFirstPVWithID(id);

I need to populate the index-class property of that target object. Are there
more efficient ways?

Thanks,

Jan

After other duties I am back :-) 

Looking into the code accessing arbitrary FO objects inside specific
LayoutManager is impossible.

I've made some experiments and what seems to be a viable option is storing
index-specific FO properties (when processing particular FO in
object-specific LayoutManager) into a map inside
AbstractPageSequenceLayoutManager and access this map via new public getter,
e.g. getPSLM().getIndexKeyReferenceInfoMap()

For final validation of this approach I need to implement some other
changes, but I need some help. I'll create separate threads.
