Class IndexedLocalFileSystem

java.lang.Object

ghidra.framework.store.local.LocalFileSystem

ghidra.framework.store.local.IndexedLocalFileSystem

All Implemented Interfaces:

FileSystem

Direct Known Subclasses:

IndexedV1LocalFileSystem

public class IndexedLocalFileSystem
extends LocalFileSystem

IndexedLocalFileSystem implements a case-sensitive indexed filesystem which uses a shallow storage hierarchy with no restriction on file name or path length. This filesystem is identified by the existence of an index file (~index.dat) and recovery journal (~index.jrn).
