Class CloudStorageFileSystem (0.123.28)

Google Cloud Storage FileSystem implementation. See Also: Concepts and Terminology, Bucket and Object Naming Guidelines

Returns Google Cloud Storage FileSystem object for bucket.

NOTE: You may prefer to use Java's standard API instead:

 FileSystem fs = FileSystems.getFileSystem(URI.create("gs://bucket"));
 

However some systems and build environments might be flaky when it comes to Java SPI. This is because services are generally runtime dependencies and depend on a META-INF file being present in your jar (generated by Google Auto at compile-time). In such cases, this method provides a simpler alternative. See Also: #forBucket(String, CloudStorageConfiguration), java.nio.file.FileSystems#getFileSystem(java.net.URI)

Creates new file system instance for bucket, with customizable settings. See Also: #forBucket(String)

Returns Google Cloud Storage FileSystem object for bucket.

Google Cloud Storage file system objects are basically free. You can create as many as you want, even if you have multiple instances for the same bucket. There's no actual system resources associated with this object. Therefore calling #close() on the returned value is optional.

Note: It is also possible to instantiate this class via Java's FileSystems.getFileSystem(URI.create("gs://bucket")). We discourage you from using that if possible, for the reasons documented in CloudStorageFileSystemProvider#newFileSystem(URI, java.util.Map) See Also: java.nio.file.FileSystems#getFileSystem(URI)

Lists the project's buckets. Pass "null" to use the default project.

Example of listing buckets, specifying the page size and a name prefix.

 String prefix = "bucket_";
 Page<Bucket> buckets = CloudStorageFileSystem.listBuckets("my-project", BucketListOption.prefix(prefix));
 Iterator<Bucket> bucketIterator = buckets.iterateAll();
 while (bucketIterator.hasNext()) {
   Bucket bucket = bucketIterator.next();
   // do something with the bucket
 }
 

Returns Cloud Storage bucket name being served by this file system.

Does nothing currently. This method might be updated in the future to close all channels associated with this file system object. However it's unlikely that even then, calling this method will become mandatory.

Returns configuration object for this file system instance.

Returns nothing because Google Cloud Storage doesn't have disk partitions of limited size, or anything similar.

Converts Cloud Storage object name to a Path object.

Returns {@value UnixPath#SEPARATOR}.

Throws UnsupportedOperationException because this feature hasn't been implemented yet.

Returns true, even if you previously called the #close() method.

Returns false.
