InvalidatingPagingSourceFactory


public final class InvalidatingPagingSourceFactoryObject, Value extends Object> implements PagingSourceFactory

Wrapper class for a PagingSource factory intended for usage in Pager construction.

Calling invalidate on this InvalidatingPagingSourceFactory will forward invalidate signals to all active PagingSources that were produced by calling invoke.

This class is thread-safe for concurrent calls to any mutative operations including both invoke and invalidate.
