All Implemented Interfaces:

FileSystem

public class IndexedV1LocalFileSystem
extends IndexedLocalFileSystem

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).

 boolean create)
                            throws IOException

Constructor.

Parameters:

rootPath - path for root directory.

isVersioned - if true item versioning will be enabled.

readOnly - if true modifications within this file-system will not be allowed and result in an ReadOnlyException

enableAsyncronousDispatching - if true a separate dispatch thread will be used to notify listeners. If false, blocking notification will be performed.

create - if true a new folder will be created.

Throws:

FileNotFoundException - if specified rootPath does not exist

IOException - if error occurs while reading/writing index files

Method Details
