Method Detail

ofSize

default SetArbitrary<T> ofSize(int size)

Fix the size to size.

Specified by:

ofSize in interface SizableArbitrary<T>

Specified by:

ofSize in interface StreamableArbitrary<T,java.util.Set<T>>

Parameters:

size - The size of the generated set

Returns:

new arbitrary instance

ofMinSize

SetArbitrary<T> ofMinSize(int minSize)

Set lower size boundary minSize (included).

Specified by:

ofMinSize in interface SizableArbitrary<T>

Specified by:

ofMinSize in interface StreamableArbitrary<T,java.util.Set<T>>

Parameters:

minSize - The minimum size of the generated set

Returns:

new arbitrary instance

ofMaxSize

SetArbitrary<T> ofMaxSize(int maxSize)

Set upper size boundary maxSize (included).

Specified by:

ofMaxSize in interface SizableArbitrary<T>

Specified by:

ofMaxSize in interface StreamableArbitrary<T,java.util.Set<T>>

Parameters:

maxSize - The maximum size of the generated set

Returns:

new arbitrary instance

mapEach

@API(status=MAINTAINED,
     since="1.4.0")
<U> Arbitrary<java.util.Set<U>> mapEach(java.util.function.BiFunction<java.util.Set<T>,T,U> mapper)

Map over each element of the generated streamable giving access to the all elements when streaming.

Type Parameters:

U - The target type of a set to generate

Parameters:

mapper - Mapper function to element type U

Returns:

arbitrary of a set of Us

flatMapEach

@API(status=MAINTAINED,
     since="1.4.0")
<U> Arbitrary<java.util.Set<U>> flatMapEach(java.util.function.BiFunction<java.util.Set<T>,T,Arbitrary<U>> flatMapper)

Flat-map over each element of the generated streamable giving access to the all elements when streaming.

Type Parameters:

U - The target type of a set to generate

Parameters:

flatMapper - Mapper function to arbitrary of element type U

Returns:

arbitrary of a set of Us

uniqueElements

@API(status=MAINTAINED,
     since="1.4.0")
SetArbitrary<T> uniqueElements(java.util.function.Function<T,java.lang.Object> by)

Add the constraint that elements of the generated set 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.

Returns:

new arbitrary instance
