public final class Jimfs extends Object
Configuration
. Basic UNIX,
Mac OS X and Windows
configurations are provided.
Examples:
// A file system with a configuration similar to the current OS FileSystem fileSystem = Jimfs.newFileSystem(); // A file system with paths and behavior generally matching that of Windows FileSystem windows = Jimfs.newFileSystem(Configuration.windows());
Additionally, various behavior of the file system can be customized by creating a custom
Configuration
. A modified version of one of the existing default configurations can be
created using Configuration.toBuilder()
or a new configuration can be created from
scratch with Configuration.builder(PathType)
. See Configuration.Builder
for what
can be configured.
Examples:
// Modify the default UNIX configuration FileSystem fileSystem = Jimfs.newFileSystem(Configuration.unix() .toBuilder() .setAttributeViews("basic", "owner", "posix", "unix") .setWorkingDirectory("/home/user") .setBlockSize(4096) .build()); // Create a custom configuration Configuration config = Configuration.builder(PathType.windows()) .setRoots("C:\\", "D:\\", "E:\\") // ... .build();

public static final String URI_SCHEME
public static FileSystem newFileSystem()
More specifically, if the operating system is Windows, Configuration.windows()
is
used; if the operating system is Mac OS X, Configuration.osX()
is used; otherwise,
Configuration.unix()
is used.
public static FileSystem newFileSystem(String name)
More specifically, if the operating system is Windows, Configuration.windows()
is
used; if the operating system is Mac OS X, Configuration.osX()
is used; otherwise,
Configuration.unix()
is used.
The returned file system uses the given name as the host part of its URI and the URIs of
paths in the file system. For example, given the name my-file-system
, the file
system's URI will be jimfs://my-file-system
and the URI of the path /foo/bar
will be jimfs://my-file-system/foo/bar
.
public static FileSystem newFileSystem(Configuration configuration)
public static FileSystem newFileSystem(String name, Configuration configuration)
The returned file system uses the given name as the host part of its URI and the URIs of
paths in the file system. For example, given the name my-file-system
, the file
system's URI will be jimfs://my-file-system
and the URI of the path /foo/bar
will be jimfs://my-file-system/foo/bar
.
