Scan an eclipse project from an eclipse plugin

I'd like to write a plugin for eclipse that performs some operations on an eclipse project.

My question is: how can I scan/obtain the project file list from an eclipse plugin???

Is there something like findfirst / findnext?

Any pointer in the right direction will be appreciated.

Ciao and thanks.

Iterating over your workspace's projects can be done through org.eclipse.core.resources.ResourcesPlugin.getWorkspace().getRoot().getProjects()

After that, finding the files you want can be done through a number of ways, easiest would be through IProjet.members(...)

Since the workspace, projects and folders all implement IResource, you can use of the org.eclipse.core.resources.IResource.accept() methods to iterate over the contents.
