Re: [jdt-core-dev] JavaModel on Eclipse start/stop

[Cristian Amitroaie <cristian@xxxxxxx>]

   Should I understand that if the package explorer is not open and Eclipse is 
closed, the "memento" state of the JavaModel is no longer up to date? And 
more than a delta between Eclipse invocations is required to recreate the 
model? In other words a full scan of the workspace is required?

   If I got it right, the JavaModel is shared between builder, indexer and 
various views. Isn't it?

   BTW, is there a document presenting the whole JDT architecture (including 
views and models relationships)? At least the conceptual level, not the 
actual classes.

Thanks, Cristian
