PagingSource.LoadResult.Invalid

public final class PagingSource.LoadResult.Invalid<Key extends Object, Value extends Object> extends PagingSource.LoadResult

Invalid result object for PagingSource.load

This return type can be used to terminate future load requests on this PagingSource when the PagingSource is not longer valid due to changes in the underlying dataset.

For example, if the underlying database gets written into but the PagingSource does not invalidate in time, it may return inconsistent results if its implementation depends on the immutability of the backing dataset it loads from (e.g., LIMIT OFFSET style db implementations). In this scenario, it is recommended to check for invalidation after loading and to return LoadResult.Invalid, which causes Paging to discard any pending or future load requests to this PagingSource and invalidate it.

Returning Invalid will trigger Paging to invalidate this PagingSource and terminate any future attempts to load from this PagingSource
