Reorganized scaladoc model
Since the old model was "interruptible", it was prone to something
similar to race conditions -- where the model was creating a template,
that template creating was interrupted to creat another template, and
so on until a cycle was hit -- then, the loop would be broken by
returning the originally not-yet-finished template.
Now everything happens in a depth-first order, starting from root,
traversing packages and classes all the way to members. The previously
interrupting operations are now grouped in two categories:
- those that were meant to add entities, like inheriting a class from
a template to the other (e.g. trait T { class C }; trait U extends T)
=> those were moved right after the core model creation
- those that were meant to do lookups - like finding the companion
object -- those were moved after the model creation and inheritance
and are not allowed to create new documentable templates.
Now, for the documentable templates we have:
DocTemplateImpl - the main documentable template, it represents a
Scala template (class, trait, object or package).
It may only be created when modelFinished=false by
methods in the modelCreation object
NoDocTemplateMemberImpl - a non-documented (source not present)
template that was inherited. May be used as
a member, but does not get its own page
NoDocTemplateImpl - a non-documented (source not present) template
that may not be used as a member and does not
get its own page
For model users: you can use anything in the ModelFactory trait at
will, but not from the modelCreation object -- that is reserved for the
core model creation and using those functions may lead to duplicate
templates, invalid links and other ugly problems.
