Class RemoteFileSystem

java.lang.Object

ghidra.framework.store.remote.RemoteFileSystem

All Implemented Interfaces:

RemoteAdapterListener, FileSystem

public class RemoteFileSystem
extends java.lang.Object
implements FileSystem, RemoteAdapterListener

RemoteFileSystem provides access to versioned FolderItem's which exist within a Repository-based directory structure. FolderItem caching is provided by the remote implementation which is intended to be shared across multiple clients.

FolderItem's must be checked-out to create new versions.

FileSystemListener's will be notified of all changes made within the Repository.
