Method Details

size

public EnumSetGeneratorSpec<E> size(int size)

Description copied from interface: EnumSetGeneratorSpec

Size of EnumSet to generate.

Specified by:

size in interface EnumSetGeneratorSpec<E extends Enum<E>>

Parameters:

size - of EnumSet

Returns:

spec builder

minSize

public EnumSetGeneratorSpec<E> minSize(int size)

Description copied from interface: EnumSetGeneratorSpec

Minimum size of EnumSet to generate.

Specified by:

minSize in interface EnumSetGeneratorSpec<E extends Enum<E>>

Parameters:

size - minimum size (inclusive)

Returns:

spec builder

maxSize

public EnumSetGeneratorSpec<E> maxSize(int size)

Description copied from interface: EnumSetGeneratorSpec

Maximum size of EnumSet to generate.

Specified by:

maxSize in interface EnumSetGeneratorSpec<E extends Enum<E>>

Parameters:

size - maximum size (inclusive)

Returns:

spec builder

of

@SafeVarargs
public final EnumSetGeneratorSpec<E> of(E... elements)

Description copied from interface: EnumSetGeneratorSpec

Specifies choices from which the EnumSet will be generated.

Specified by:

of in interface EnumSetGeneratorSpec<E extends Enum<E>>

Parameters:

elements - from which the enum set will be generated

Returns:

spec builder

excluding

@SafeVarargs
public final EnumSetGeneratorSpec<E> excluding(E... elements)

Description copied from interface: EnumSetGeneratorSpec

Specifies enum values to exclude from the generated EnumSet.

Specified by:

excluding in interface EnumSetGeneratorSpec<E extends Enum<E>>

Parameters:

elements - to excluding from the generated enum set

Returns:

spec builder

generate

public EnumSet<E> generate(Random random)

Description copied from interface: Generator

Returns a generated value.

If this method produces random data, the data needs to be generated using the provided Random instance. This ensures generated values are reproducible for a given seed value.

Specified by:

generate in interface Generator<E extends Enum<E>>

Parameters:

random - provider for generating random values

Returns:

generated value or null if value is nullable, could not be generated, or generation is delegated to the engine

hints

public Hints hints()

Description copied from interface: Generator

Hints provided by the generator to the engine.

The most important hint for custom generators is AfterGenerate. This hint indicates whether the object created by this generator:

• should be populated (for example, if it has null fields)
• can be modified using selectors

For example, setting the hint to AfterGenerate.POPULATE_NULLS will cause Instancio to populate null fields on the object returned by this generator:

   @Override
   public Hints hints() {
       return Hints.afterGenerate(AfterGenerate.POPULATE_NULLS);
   }
 

If the action is not specified, default behaviour will be based on the AfterGenerate value configured in the Settings using the key Keys.AFTER_GENERATE_HINT.

In addition, the following hints can be provided for populating data structures:

• ArrayHint
• CollectionHint
• MapHint

Specified by:

hints in interface Generator<E extends Enum<E>>

Overrides:

hints in class AbstractGenerator<EnumSet<E extends Enum<E>>>

Returns:

hints from this generator to the engine
