uproot.source.object.ObjectResource

Defined in uproot.source.object on line 18.

Inheritance order:

  1. uproot.source.chunk.Resource
class uproot.source.object.ObjectResource(obj)
Parameters:

obj – The file-like object to use.

A uproot.source.chunk.Resource for a file-like object.

This object must have the following methods:

  • read(num_bytes) where num_bytes is an integer number of bytes to read.

  • seek(position) where position is an integer position to seek to.

Both of these methods change the internal state of the object, its current seek position (because read moves that position forward num_bytes). Hence, it is in principle not thread-safe.

obj

ObjectResource.obj

closed

ObjectResource.closed

get

ObjectResource.get(start: int, stop: int)
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 ObjectResource.future(source: Source, start: int, stop: int)
Parameters:

  • source (uproot.ObjectSource) – 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.

file_path

Inherited from uproot.source.chunk.Resource.

ObjectResource.file_path

A path to the file (or URL).
