◆ get()

Sample pulsatrix::TransformDataset::get ( int64_t index ) const

inlineoverridevirtual

Loads one sample by index.

Parameters

index Sample index, must be in [0, size()).

Returns: The sample at index.

Exceptions

std::out_of_range if index is out of bounds – external boundary: the index is chosen by a Sampler/DataLoader from possibly-external configuration (shuffle seed, resumed epoch offset), not a compile-time-known loop bound.

Implements pulsatrix::Dataset.

◆ size()
