abstract create_dir(self, path, recursive)#

Implement PyFileSystem.create_dir(…).

Parameters:

pathstr

path of the directory.

recursivebool

if the parent directories should be created too.

abstract delete_dir(self, path)#

Implement PyFileSystem.delete_dir(…).

Parameters:

pathstr

path of the directory.

Implement PyFileSystem.delete_dir_contents(…).

Parameters:

pathstr

path of the directory.

if False an error should be raised if path does not exist

abstract delete_file(self, path)#

Implement PyFileSystem.delete_file(…).

Parameters:

pathstr

path of the file.

abstract delete_root_dir_contents(self)#

Implement PyFileSystem.delete_dir_contents(“/”, accept_root_dir=True).

abstract get_file_info(self, paths)#

Implement PyFileSystem.get_file_info(paths).

Parameters:

pathslist of str

paths for which we want to retrieve the info.

abstract get_file_info_selector(self, selector)#

Implement PyFileSystem.get_file_info(selector).

Parameters:

selectorFileSelector

selector for which we want to retrieve the info.

abstract get_type_name(self)#

Implement PyFileSystem.type_name.

abstract move(self, src, dest)#

Implement PyFileSystem.move(…).

Parameters:

srcstr

path of what should be moved.

deststr

path of where it should be moved to.

abstract normalize_path(self, path)#

Implement PyFileSystem.normalize_path(…).

pathstr

path of what should be opened.

abstract open_output_stream(self, path, metadata)#

Implement PyFileSystem.open_output_stream(…).

Parameters:

pathstr

path of what should be opened.

metadatamapping

Mapping of string keys to string values. Some filesystems support storing metadata along the file (such as “Content-Type”).
