org.aspectj.org.eclipse.jdt.internal.core.nd.indexer.FileStateCache
public class FileStateCache extends Object
Holds a cache that maps filenames (absolute paths on the local filesystem) to "up to date" states. A file is "up to date" if its content is known to be in sync with the index. A file is not up to date if there is any possibility that its content might be out of sync with the index.
