ItemKeyedDataSource.LoadCallback

The android.arch Architecture Components packages are no longer maintained. They have been superseded by the corresponding androidx.* packages. See androidx.paging.ItemKeyedDataSource.LoadCallback instead.

public static abstract class ItemKeyedDataSource.LoadCallback
extends Object

java.lang.Object
↳	android.arch.paging.ItemKeyedDataSource.LoadCallback<Value>

Known direct subclasses

ItemKeyedDataSource.LoadInitialCallback<Value>

ItemKeyedDataSource.LoadInitialCallback<Value> Callback for loadInitial(LoadInitialParams, LoadInitialCallback) to return data and, optionally, position/count information.

Callback for ItemKeyedDataSource loadBefore(LoadParams, LoadCallback) and loadAfter(LoadParams, LoadCallback) to return data.

A callback can be called only once, and will 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).
