class imagedata.transports.abstracttransport.AbstractTransport(name: str, description: str, authors: str, version: str, url: str, schemes: List[str] | None = None)[source]

Abstract base class definition for imagedata transport plugins. Plugins must be a subclass of AbstractPlugin and must define the attributes set in __init__() and the following methods:

open() method isfile() method walk() method

property authors: str

Plugin authors

Multi-line string naming the author(s) of the plugin.

abstract close()[source]

Close the transport

property description: str

Plugin description

Single line string describing the transport method.

abstract exists(path: str) bool[source]

Determine whether the named path exists.

abstract info(path) str[source]

Return info describing the object

Parameters:

path (str) – object path

Returns:

Preferably a one-line string describing the object

Return type:

description (str)

abstract isfile(path: str) bool[source]

Return True if path is an existing regular file.

property name: str

Plugin name

Single word string describing the image format. Typical names: file, dicom, xnat

abstract open(path: str, mode: str = 'r') IOBase[source]

Extract a member from the archive as a file-like object.

property schemes: List[str]

List of transport schemes supported by this plugin.

List of strings.

property url: str

Plugin URL

URL string to the site of the plugin or the author(s).

property version: str

Plugin version

String giving the plugin version. Version scheme: 1.0.0

info(path) str[source]

Return info describing the object

Parameters:

path (str) – object path

Returns:

Preferably a one-line string describing the object

Return type:

description (str)

isfile(path)[source]

Return True if path is an existing regular file.

open(path, mode='r')[source]

Extract a member from the archive as a file-like object.

store(ds)[source]

Store DICOM dataset using DICOM Storage SCU protocol.

walk(top)[source]

Generate the file names in a directory tree by walking the tree. Input: - top: starting point for walk (str) Return: - tuples of (root, dirs, files)

Module imagedata.transports.filetransport

Read/Write local files

class imagedata.transports.filetransport.FileTransport(netloc: str | None = None, root: str | None = None, mode: str | None = 'r', read_directory_only: bool | None = False, opts: dict | None = None)[source]

Read/write local files.

Parameters:
  • netloc (str) – Not used.

  • root (str) – Root path.

  • mode (str) – Filesystem access mode.

  • read_directory_only (bool) – Whether root should refer to a directory.

  • opts (dict) – Options

Returns:

FileTransport instance

Raises:
  • RootIsNotDirectory – when the root is not a directory when read_directory_only is True.

  • FileNotFoundError – Specified root does not exist.

  • AssertionError – When root is None.

close()[source]

Close the transport

exists(path)[source]
