Introduction

What is libjimfs-java

libjimfs-java is:

Jimfs is an in-memory file system for Java 7 and above, implementing the java.nio.file abstract file system APIs. Jimfs supports almost all the APIs under java.nio.file. It supports:

  • Creating, deleting, moving and copying files and directories.
  • Reading and writing files with FileChannel or SeekableByteChannel, InputStream, OutputStream, etc. Symbolic links.
  • Hard links to regular files.
  • SecureDirectoryStream, for operations relative to an open directory.
  • Glob and regex path filtering with PathMatcher.
  • Watching for changes to a directory with a WatchService.
  • File attributes. Built-in attribute views that can be supported include “basic”, “owner”, “posix”, “unix”, “dos”, “acl” and “user”. Do note, however, that not all attribute views provide useful attributes.

For example, while setting and reading POSIX file permissions is possible with the “posix” view, those permissions will not actually affect the behavior of the file system.

Jimfs also supports creating file systems that, for example, use Windows-style paths and (to an extent) behavior. In general, however, file system behavior is modeled after UNIX and may not exactly match any particular real file system or platform.

NOTE: SystemJimfsFileSystemProvider is not fully included in this package, because it requires a library that is not yet in Debian.
