NetBeans internally uses the concept of a virtual filesystem. This module provide APIs for accessing such virtual files as well as some support classes to make writing of custom vitual filesystems easier.
What is New (see all changes)?
- May 28 '15 Pluggable archive files support for FileUtil
To support JDK 9 image file as an archive the FileUtil's method
getArchiveFile,getArchiveRootandisArchiveFileare pluggable using a new SPIArchiveFileProvider. In addition to these methods a new methodisArchiveArtifactwas added. This method can be used if givenURLpoints into an archive. - Feb 25 '15 Support for multi-user environments
To support multiple configurations (users, profiles, ...) executing in the same VM, multiple Repositories can be created, one for each execution context. API has been added to acquire and SPI to create a local Repository which holds config filesystem for the execution thraed.
- Nov 27 '14 Support detection and reading of symbolic links.
Add methods to
FileObjectfor handling of symbolic links:-
isSymbolicLink() -
readSymbolicLink() -
readSymbolicLinkPath() -
getCanonicalFileObject()
Add utility method to
FileUtilfor dealing with recursive symbolic links.-
isRecursiveSymbolicLink()
Introduce new interface AbstractFileSystem.SymlinkInfo.
-
- Nov 10 '14 FileLock implements AutoCloseable
FileLock implements AutoCloseable to work well in try-with-resources constructs.
- Oct 3 '14 FileSystem.Status API removed
The FileSystem.Status was entirely removed, as it references class java.awt.Image, which is not available in compact jdk profiles and may trigger GUI system initialization. See javadocs of StatusDecorator for details.
Use Cases
For general overview of the filesystem concepts, related topics,
together with code samples, see chapter 3,
of NetBeans Platform for Beginners
by Jason Wexbridge and Walter Nyland.
Many of the usecases are described at the
overall documentation,
in a way how to
register a mime type.
Some of the additional usecases are covered here.
How to change menus, etc. after login?
See documentation about dynamically changing the system filesystem.
