[platform-core-dev] Flexible Resource Model use case

["Terence Parker" <eclipse.tparker@xxxxxxxxx>]

I haven't seen the following use case yet so I want to add it to the discussion.

• A project needs to pull in code that is rooted in folder "A1"
• A1 is outside the user's workspace
• A1 contains many subfolders
  
• Only a handful of A1's subfolders are a part of the project
• IFolder.createLink() is called, linking the project to folder A1
  
• IFolder.createLink() starts a refresh that traverses _everything_ under A1
• The cost of traversing all of A1's subfolders is too high--IResource.setHidden() can only be called on subfolders after they have been pulled into the workspace
  

We
need a way to hook into the resource delta creation so that any nested subfolder can be hidden _before_ that
subfolder is traversed.
