| === What is a FileObject? |
| |
| FileObjects are _virtual files_ which live inside a link:DevFaqFileSystem.asciidoc[FileSystem ]. They |
| may represent a file on disk - or anything else walks and talks like a file, or can be made to - such as a file |
| on a remote FTP server, a file entry in a JAR file, an entry in an XML file, etc. |
| |
| FileObjects differ from `java.io.File` in certain ways: |
| |
| * You don't generally ever have a FileObject representing a file that doesn't really exist (if you think a FileObject may have been deleted, check `isValid()`) |
| * You can listen for changes on FileObjects |
| * `FileObjects` can have key-value pairs of ad-hoc link:DevFaqFileAttributes.asciidoc[attributes ] associated with them |
| |
| They are part of the link:http://bits.netbeans.org/dev/javadoc/org-openide-filesystems/org/openide/filesystems/doc-files/api.html[Filesystems API]; |
| the javadoc for FileObject can be found link:http://bits.netbeans.org/dev/javadoc/org-openide-filesystems/org/openide/filesystems/FileObject.html[here]. |
