Defined in uproot.source.xrootd on line 82.

Inheritance order:

  1. uproot.source.chunk.Resource
class uproot.source.xrootd.XRootDResource(file_path: str, timeout: float | None)
Parameters:

  • file_path (str) – A URL of the file to open.

  • timeout (None or float) – An optional timeout in seconds.

A uproot.source.chunk.Resource for XRootD connections.

timeout

XRootDResource.timeout

The timeout in seconds or None.

file

XRootDResource.file

The XRootD.client.File object.

num_bytes

XRootDResource.num_bytes

closed

XRootDResource.closed

get

XRootDResource.get(start: int, stop: int) → bytes
Parameters:

  • start (int) – Seek position of the first byte to include.

  • stop (int) – Seek position of the first byte to exclude (one greater than the last byte to include).

Returns a Python buffer of data between start and stop.

future

static XRootDResource.future(source: Source, start: int, stop: int)
Parameters:

  • source (uproot.MultithreadedXRootDSource) – The data source.

  • start (int) – Seek position of the first byte to include.

  • stop (int) – Seek position of the first byte to exclude (one greater than the last byte to include).

Returns a uproot.source.futures.ResourceFuture that calls get with start and stop.

partfuture

static XRootDResource.partfuture(results, start: int, stop: int)

Returns a uproot.source.futures.ResourceFuture to simply select the (start, stop) item from the results dict.

In chunks, each chunk has a partfuture that are collectively filled by callbacks from callbacker.

mergefuture

static XRootDResource.mergefuture(partfutures)

Returns a uproot.source.futures.ResourceFuture that merges the chunks previously submitted via partfuture which had to be split

callbacker

XRootDResource.callbacker(futures, results)

Returns an XRootD callback function to fill the futures and results.

file_path

Inherited from uproot.source.chunk.Resource.

XRootDResource.file_path

A path to the file (or URL).
