PositionalDataSource.LoadRangeCallback

Added in 2.0.0
Deprecated in 3.0.0

public abstract class PositionalDataSource.LoadRangeCallback<T extends Object>


Callback for PositionalDataSource loadRange 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).

Parameters
<T extends Object>

Type of items being loaded.
