     .setRequestConditions(requestConditions);

 Response<Boolean> response = client.deleteSubdirectoryIfExistsWithResponse(directoryName, options,
     timeout, new Context(key1, value1));
 if (response.getStatusCode() == 404) {
     System.out.println("Does not exist.");
 } else {
     System.out.printf("Delete completed with status %d%n", response.getStatusCode());
 }
      Parameters:
      subdirectoryName - Name of the sub-directory to delete.
      options - DataLakePathDeleteOptions
      timeout - An optional timeout value beyond which a RuntimeException will be raised.
      context - Additional context that is passed through the Http pipeline during the service call.
      Returns:
      A response containing status code and HTTP headers. If Response's status code is 200, the specified subdirectory was successfully deleted. If status code is 404, the specified subdirectory does not exist.

    • rename

      public DataLakeDirectoryClient rename(String destinationFileSystem, String destinationPath)
      Moves the directory to another location within the file system. For more information see the Azure Docs.

      Code Samples

       DataLakeDirectoryClient renamedClient = client.rename(fileSystemName, destinationPath);
 System.out.println("Directory Client has been renamed");
      Parameters:
      destinationFileSystem - The file system of the destination within the account. null for the current file system.
      destinationPath - Relative path from the file system to rename the directory to, excludes the file system name. For example if you want to move a directory with fileSystem = "myfilesystem", path = "mydir/mysubdir" to another path in myfilesystem (ex: newdir) then set the destinationPath = "newdir"
      Returns:
      A DataLakeDirectoryClient used to interact with the new directory created.

    • renameWithResponse

      public com.azure.core.http.rest.Response<DataLakeDirectoryClient> renameWithResponse(String destinationFileSystem, String destinationPath, DataLakeRequestConditions sourceRequestConditions, DataLakeRequestConditions destinationRequestConditions, Duration timeout, com.azure.core.util.Context context)
      Moves the directory to another location within the file system. For more information, see the Azure Docs.

      Code Samples

       DataLakeRequestConditions sourceRequestConditions = new DataLakeRequestConditions()
     .setLeaseId(leaseId);
 DataLakeRequestConditions destinationRequestConditions = new DataLakeRequestConditions();

 DataLakeDirectoryClient newRenamedClient = client.renameWithResponse(fileSystemName, destinationPath,
     sourceRequestConditions, destinationRequestConditions, timeout, new Context(key1, value1)).getValue();
 System.out.println("Directory Client has been renamed");
      Parameters:
      destinationFileSystem - The file system of the destination within the account. null for the current file system.
      destinationPath - Relative path from the file system to rename the directory to, excludes the file system name. For example if you want to move a directory with fileSystem = "myfilesystem", path = "mydir/mysubdir" to another path in myfilesystem (ex: newdir) then set the destinationPath = "newdir"
      sourceRequestConditions - DataLakeRequestConditions against the source.
      destinationRequestConditions - DataLakeRequestConditions against the destination.
      timeout - An optional timeout value beyond which a RuntimeException will be raised.
      context - Additional context that is passed through the Http pipeline during the service call.
      Returns:
      A Response whose value that contains a DataLakeDirectoryClient used to interact with the directory created.

    • listPaths

      public com.azure.core.http.rest.PagedIterable<PathItem> listPaths()
      Returns a lazy loaded list of files/directories in this directory. The returned PagedIterable can be consumed while new items are automatically retrieved as needed. For more information, see the Azure Docs.

      Code Samples

       client.listPaths().forEach(path -> System.out.printf("Name: %s%n", path.getName()));
      Returns:
      The list of files/directories.

    • listPaths

      public com.azure.core.http.rest.PagedIterable<PathItem> listPaths(boolean recursive, boolean userPrincipleNameReturned, Integer maxResults, Duration timeout)
      Returns a lazy loaded list of files/directories in this directory. The returned PagedIterable can be consumed while new items are automatically retrieved as needed. For more information, see the Azure Docs.

      Code Samples

       client.listPaths(false, false, 10, timeout)
     .forEach(path -> System.out.printf("Name: %s%n", path.getName()));
      Parameters:
      recursive - Specifies if the call should recursively include all paths.
      userPrincipleNameReturned - If "true", the user identity values returned in the x-ms-owner, x-ms-group, and x-ms-acl response headers will be transformed from Azure Active Directory Object IDs to User Principal Names. If "false", the values will be returned as Azure Active Directory Object IDs. The default value is false. Note that group and application Object IDs are not translated because they do not have unique friendly names.
      maxResults - Specifies the maximum number of blobs to return per page, including all BlobPrefix elements. If the request does not specify maxResults or specifies a value greater than 5,000, the server will return up to 5,000 items per page. If iterating by page, the page size passed to byPage methods such as ContinuablePagedIterable.iterableByPage(int) will be preferred over this value.
      timeout - An optional timeout value beyond which a RuntimeException will be raised.
      Returns:
      The list of files/directories.
