Overview

Callback for PositionalDataSource PositionalDataSource.loadRange(PositionalDataSource.LoadRangeParams, PositionalDataSource.LoadRangeCallback) to return data.

A callback should be called only once, and may throw if called again.

It is always valid for a DataSource loading method that takes a callback to stash the callback and call it later. This enables DataSources to be fully asynchronous, and to handle temporary, recoverable error states (such as a network error that can be retried).
