SampleDataset

class SampleDataset(dataset: Dataset, df: DataFrame)

Bases: Dataset

A specialized Dataset class for representing a sample of records.

This class is typically instantiated via the sample method of the base Dataset. It maintains a reference to the original dataset’s metadata while holding only a sample of the data.

Parameters:

• dataset (Dataset) – The parent Dataset instance from which this sample was derived.

• df (DataFrame) – The sampled data records.

Variables:

all_sample_datasets (list) – A class-level list containing all instantiated SampleDataset objects.

Methods

reload_df()

Unlike the base Dataset class, a SampleDataset cannot easily “reload” from disk because it is a result of an in-memory sampling operation. Thus, consider re-running the logic from Dataset.sample instead.

Returns:

ITableDF – The currently held sampled data.

Attributes

all_sample_datasets
df	Access the sampled data.

all_sample_datasets = []

df

Access the sampled data.

Returns:

ITableDF – The sampled data.
