MapGenerator

public MapGenerator(GeneratorContext context)

Method Details

subtype

public MapGeneratorSpec<K,V> subtype(Class<?> type)

Description copied from interface: MapGeneratorSpec

Specifies the type of map that should be generated.

Specified by:

subtype in interface MapGeneratorSpec<K,V>

Parameters:

type - of collection to generate

Returns:

spec builder

size

public MapGeneratorSpec<K,V> size(int size)

Description copied from interface: MapGeneratorSpec

Size of map to generate.

Specified by:

size in interface MapGeneratorSpec<K,V>

Parameters:

size - of map

Returns:

spec builder

minSize

public MapGeneratorSpec<K,V> minSize(int size)

Description copied from interface: MapGeneratorSpec

Minimum size of map to generate.

Specified by:

minSize in interface MapGeneratorSpec<K,V>

Parameters:

size - minimum size (inclusive)

Returns:

spec builder

maxSize

public MapGeneratorSpec<K,V> maxSize(int size)

Description copied from interface: MapGeneratorSpec

Maximum size of map to generate.

Specified by:

maxSize in interface MapGeneratorSpec<K,V>

Parameters:

size - maximum size (inclusive)

Returns:

spec builder

nullable

public MapGeneratorSpec<K,V> nullable()

Description copied from interface: MapGeneratorSpec

Indicates that null value can be generated for the map.

Specified by:

nullable in interface MapGeneratorSpec<K,V>

Returns:

spec builder

nullableKeys

public MapGeneratorSpec<K,V> nullableKeys()

Description copied from interface: MapGeneratorSpec

Indicates that null values can be generated for map keys.

Specified by:

nullableKeys in interface MapGeneratorSpec<K,V>

Returns:

spec builder

nullableValues

public MapGeneratorSpec<K,V> nullableValues()

Description copied from interface: MapGeneratorSpec

Indicates that null values can be generated for map values.

Specified by:

nullableValues in interface MapGeneratorSpec<K,V>

Returns:

spec builder

generate

public Map<K,V> generate(Random random)

Description copied from interface: Generator

Returns a generated value.

If the generated value is random, it needs to be generated using the given Random instance. This ensures the data is generated with the same seed value and allows random data to be reproduced by specifying the seed value.

Specified by:

generate in interface Generator<K>

Parameters:

random - provider for random values

Returns:

generated value

getHints

public GeneratedHints getHints()

Description copied from interface: Generator

Returns hints, including collection sizes and whether values are nullable.

Specified by:

getHints in interface Generator<K>

Returns:

generated hints
