uproot.interpretation.jagged.JaggedArray

class uproot.interpretation.jagged.JaggedArray(offsets, content)

Parameters:

offsets (array of numpy.int32) – Starting and stopping entries for each variable-length list. The length of the offsets is one greater than the number of lists.
content (array) – Contiguous array for data in all nested lists of the jagged array.

Temporary array filled by basket_array, which will be turned into a NumPy, Awkward, or other array, depending on the specified uproot.interpretation.library.Library.

offsets

JaggedArray.offsets: Starting and stopping entries for each variable-length list. The length of the offsets is one greater than the number of lists.

JaggedArray.content: Contiguous array for data in all nested lists of the jagged array.

JaggedArray.parents_localindex(entry_start, entry_stop)

Parameters:

entry_start (int) – First entry to include.
entry_stop (int) – FIrst entry to exclude (one greater than the last entry to include)

Returns the “parents” and “localindex” of this jagged array, using Awkward 0 terminology.

The “parents” is an array of integers with the same length as content that indicates which list each item belongs to.

The “localindex” is an array of integers with the same length that indicates which subentry each item is, within its nested list.
