reduce

<R extends @Nullable Object> Arbitrary<R> reduce(R initial,
 BiFunction<R,? super T,R> accumulator)

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

Typparameter:

R - The result type

Parameter:

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

Gibt zurück:

The result of accumulating all elements in streamable

ofSize

default StreamableArbitrary<T,U> ofSize(int size)

Fix the size to size.

ofMinSize

StreamableArbitrary<T,U> ofMinSize(int minSize)

Set lower size boundary minSize (included).

Angegeben von:

ofMaxSize

StreamableArbitrary<T,U> ofMaxSize(int maxSize)

Set upper size boundary maxSize (included).

withSizeDistribution

@API(status=EXPERIMENTAL,
     since="1.5.3")
StreamableArbitrary<T,U> withSizeDistribution(RandomDistribution distribution)

Set distribution distribution of size of generated arbitrary

uniqueElements

@API(status=MAINTAINED,
     since="1.7.3")
StreamableArbitrary<T,U> uniqueElements()

Add the constraint that elements of the generated streamable must be unique, i.e. no two elements must return true when being compared using Object.equals(Object).

The constraint can be combined with other uniqueElements(Function) constraints.

uniqueElements

@API(status=MAINTAINED,
     since="1.7.3")
StreamableArbitrary<T,U> uniqueElements(Function<? super T,?> by)

Add the constraint that elements of the generated streamable must be unique relating to an element's "feature" being extracted using the by function. The extracted features are being compared using Object.equals(Object).

The constraint can be combined with other uniqueElements(Function) constraints.
