This factory is used to build a resource delta that represents a proposed change that can then be passed to the validateChange(IResourceDelta, IProgressMonitor) method in order to validate the change with any model providers stored in those resources. The deltas created by calls to the methods of this interface will be the same as those generated by the workspace if the proposed operations were performed.

This factory does not validate that the proposed operation is valid given the current state of the resources and any other proposed changes. It only records the delta that would result.

This interface is not intended to be implemented by clients.
