| <p>Callback for PositionalDataSource <code><a href="/reference/kotlin/androidx/paging/PositionalDataSource.html#loadRange(androidx.paging.PositionalDataSource.LoadRangeParams)">loadRange</a></code> to return data.</p> |
| <p>A callback should be called only once, and may throw if called again.</p> |
| <p>It is always valid for a <code><a href="/reference/kotlin/androidx/paging/DataSource.html">DataSource</a></code> 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).</p> |
