Interface Cardinality.Fetcher

All Superinterfaces:

Cardinality, DataSource<Integer>, Generator<Integer>, Stringify, Supplier<Integer>, Typed<Integer>

All Known Subinterfaces:

FlCardinality.FlFetcher

All Known Implementing Classes:

AbstractFetcher, EagerFetcher, FetcherWithScalar, LazyFetcher

Enclosing interface:

Cardinality

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface Cardinality.Fetcher
extends Cardinality, Generator<Integer>

Retrieves elements from a generator. Fetching may occur eager or lazy.

The integer generated is the number of elements that would have been fetched and may be different for each call.
