has_next_batch()

virtual bool turi::activity_classification::data_iterator::has_next_batch ( ) const

pure virtual

Returns true if and only if the next call to next_batch will return a batch with size greater than 0.

Implemented in turi::activity_classification::simple_data_iterator.

next_batch()

virtual batch turi::activity_classification::data_iterator::next_batch ( size_t  batch_size )

pure virtual

Returns a batch containing float arrays with the indicated batch size.

Eventually returns a batch with size smaller than the requested size, indicating that the entire dataset has been traversed. All subsequent calls will return an empty (all padding) batch, until reset.

Implemented in turi::activity_classification::simple_data_iterator.

reset()

virtual void turi::activity_classification::data_iterator::reset ( )

pure virtual

Begins a fresh traversal of the dataset.

Implemented in turi::activity_classification::simple_data_iterator.
