Detailed Description

The Document.

Heart of everything. Actions take place here.

The Document is the main object in Okular. All views query the Document to get data/properties or even for accessing pages (in a 'const' way).

It is designed to keep it detached from the document type (pdf, ps, you name it..) so whenever you want to get some data, it asks its internal generators to do the job and return results in a format-independent way.

Apart from the generator (the currently running one) the document stores all the Pages ('Page' class) of the current document in a vector and notifies all the registered DocumentObservers when some content changes.

For a better understanding of hierarchies
