Class FilesystemStorageStrategyImpl

java.lang.Object

org.jclouds.filesystem.strategy.internal.FilesystemStorageStrategyImpl

All Implemented Interfaces:

org.jclouds.blobstore.LocalStorageStrategy

public class FilesystemStorageStrategyImpl
extends Object
implements org.jclouds.blobstore.LocalStorageStrategy

FilesystemStorageStrategyImpl implements a blob store that stores objects on the file system. Content metadata and user attributes are stored in extended attributes if the file system supports them. Directory blobs (blobs that end with a /) cannot have content, but otherwise appear in LIST like normal blobs.
