Method Summary

Modifier and Type	Method	Description
MapArbitrary<K,V>	ofMaxSize(int maxSize)	Set upper size boundary maxSize (included).
MapArbitrary<K,V>	ofMinSize(int minSize)	Set lower size boundary minSize (included).
default MapArbitrary<K,V>	ofSize(int size)	Fix the size to size.
MapArbitrary<K,V>	uniqueKeys(java.util.function.Function<K,java.lang.Object> by)	Add the constraint that keys of the generated map must be unique relating to an element's "feature" being extracted by applying the by function on a map entry's key.
MapArbitrary<K,V>	uniqueValues()	Add the constraint that values of the generated map must be unique, i.e. no two value must return true when being compared using Object.equals(Object).
MapArbitrary<K,V>	uniqueValues(java.util.function.Function<V,java.lang.Object> by)	Add the constraint that value of the generated map must be unique relating to an element's "feature" being extracted by applying the by function on a map entry's value.

Method Detail

ofSize

default MapArbitrary<K,V> ofSize(int size)

Fix the size to size.

Specified by:

ofSize in interface SizableArbitrary<K>

Parameters:

size - The size of the generated map

Returns:

new arbitrary instance

ofMinSize

MapArbitrary<K,V> ofMinSize(int minSize)

Set lower size boundary minSize (included).

Specified by:

ofMinSize in interface SizableArbitrary<K>

Parameters:

minSize - The minimum size of the generated map

Returns:

new arbitrary instance

ofMaxSize

MapArbitrary<K,V> ofMaxSize(int maxSize)

Set upper size boundary maxSize (included).

Specified by:

ofMaxSize in interface SizableArbitrary<K>

Parameters:

maxSize - The maximum size of the generated map

Returns:

new arbitrary instance

uniqueKeys

@API(status=MAINTAINED,
     since="1.4.0")
MapArbitrary<K,V> uniqueKeys(java.util.function.Function<K,java.lang.Object> by)

Add the constraint that keys of the generated map must be unique relating to an element's "feature" being extracted by applying the by function on a map entry's key. The extracted features are being compared using Object.equals(Object).

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

Returns:

new arbitrary instance

uniqueValues

@API(status=MAINTAINED,
     since="1.4.0")
MapArbitrary<K,V> uniqueValues(java.util.function.Function<V,java.lang.Object> by)

Add the constraint that value of the generated map must be unique relating to an element's "feature" being extracted by applying the by function on a map entry's value. The extracted features are being compared using Object.equals(Object).

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

Returns:

new arbitrary instance

uniqueValues

@API(status=MAINTAINED,
     since="1.4.0")
MapArbitrary<K,V> uniqueValues()

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

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

Returns:

new arbitrary instance
