Snap for 7862349 from b6b9b077d32ef9d5817a77a7fd25dc02285800bb to t-keystone-qcom-release Change-Id: I3752a8ad20bb648c8822d351e1fcae4fbb74354a
Jimfs is an in-memory file system for Java 7 and above, implementing the java.nio.file abstract file system APIs.
The latest release is 1.1.
It is available in Maven Central as com.google.jimfs:jimfs:1.1:
<dependency> <groupId>com.google.jimfs</groupId> <artifactId>jimfs</artifactId> <version>1.1</version> </dependency>
The simplest way to use Jimfs is to just get a new FileSystem
instance from the Jimfs
class and start using it:
import com.google.common.jimfs.Configuration; import com.google.common.jimfs.Jimfs; ... // For a simple file system with Unix-style paths and behavior: FileSystem fs = Jimfs.newFileSystem(Configuration.unix()); Path foo = fs.getPath("/foo"); Files.createDirectory(foo); Path hello = foo.resolve("hello.txt"); // /foo/hello.txt Files.write(hello, ImmutableList.of("hello world"), StandardCharsets.UTF_8);
Jimfs supports almost all the APIs under java.nio.file
. It supports:
FileChannel
or SeekableByteChannel
, InputStream
, OutputStream
, etc.SecureDirectoryStream
, for operations relative to an open directory.PathMatcher
.WatchService
.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.
