Example 1
/**
 * Factory method for constructing and initializing an instance of InMemoryGlobberFileSystem which
 * is ready to list/get FileStatus entries corresponding to {@code fileStatuses}.
 */
public static FileSystem createInstance(
    Configuration config, Path workingDirectory, Collection<FileStatus> fileStatuses) {
  checkNotNull(config, "configuration can not be null");

  FileSystem fileSystem = new InMemoryGlobberFileSystem(workingDirectory, fileStatuses);
  fileSystem.setConf(config);

  return fileSystem;
}
