Interface StreamableArbitrary<T,U>

All Superinterfaces:

Arbitrary<U>, SizableArbitrary<U>

@API(status=EXPERIMENTAL,
     since="1.2.1")
public interface StreamableArbitrary<T,U>
extends SizableArbitrary<U>

Fluent interface to add functionality to arbitraries whose generation artefacts can be streamed, e.g. List, Set, Stream and Arrays

Method Detail

reduce

<R> Arbitrary<R> reduce(R initial,
                        java.util.function.BiFunction<R,T,R> accumulator)

Given an initial argument use accumulator to produce the final result.

Type Parameters:

R - The result type

Parameters:

initial - The initial argument. Also the result if streamable is empty

accumulator - The function used to reduce a streamable into a result one by one

Returns:

The result of accumulating all elements in streamable
