Method Detail

ofSize

default StreamArbitrary<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.stream.Stream<T>>

Parameters:

size - The size of the generated stream

Returns:

new arbitrary instance

ofMinSize

StreamArbitrary<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.stream.Stream<T>>

Parameters:

minSize - The minimum size of the generated stream

Returns:

new arbitrary instance

ofMaxSize

StreamArbitrary<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.stream.Stream<T>>

Parameters:

maxSize - The maximum size of the generated stream

Returns:

new arbitrary instance

withSizeDistribution

@API(status=EXPERIMENTAL,
     since="1.5.3")
StreamArbitrary<T> withSizeDistribution(RandomDistribution uniform)

Set random distribution distribution of size of generated stream. The distribution's center is the minimum size of the generated stream.

Specified by:

withSizeDistribution in interface SizableArbitrary<T>

Specified by:

withSizeDistribution in interface StreamableArbitrary<T,java.util.stream.Stream<T>>

uniqueElements

@API(status=MAINTAINED,
     since="1.4.0")
StreamArbitrary<T> uniqueElements()

Add the constraint that elements of the generated stream 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.

Returns:

new arbitrary instance

uniqueElements

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

Add the constraint that elements of the generated stream 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
