Constructor Detail

RandomFactory

public RandomFactory(RandomFactory.Supplier<T> pojoSupplier)

A constructor that takes one RandomFactory.Supplier. The mapping of properties to the factories filling them is guessed.

Parameters:

pojoSupplier - the supplier for the POJO

RandomFactory

public RandomFactory(RandomFactory.Supplier<T> pojoSupplier,
                     Map<String,RandomField> fieldMapping)

A constructor that takes one class and the mapping of properties to the factories filling them.

Parameters:

pojoSupplier - the supplier for the POJO

fieldMapping - the initial mapping for the fields

Method Detail

forClass

public static <U> RandomFactory<U> forClass(Class<U> pojoClass)

Creates a RandomFactory with just one class and then tries to guess which fields to fill. Might not be the best option for some cases.

Type Parameters:

U - the class that should be generated

Parameters:

pojoClass - the class of the POJO to be created; the class must have a default constructor and be public

Returns:

a RandomFactory with guessed mapping

nextValue

public T nextValue()

Description copied from interface: RandomField

Returns a random value.

Specified by:

nextValue in interface RandomField

Returns:

a random value

createSingle

public T createSingle()
               throws RandomException

Creates a single instance of the class this factory is for.

Returns:

a single POJO instance

Throws:

RandomException - - if something went wrong

create

public List<T> create(int count)

Creates some instances of the POJO this factory is for.

Parameters:

count - number of instances to be created

Returns:

some POJO instances

Throws:

RandomException - - if something went wrong

getRandomField

public RandomField getRandomField(String property)

Returns the RandomField used to fill the property.

Parameters:

property - the property

Returns:

the random field to fill this property; never null

Throws:

RandomException - if no RandomField was found

findRandomField

public RandomField findRandomField(String property)

Returns the RandomField used to fill the property.

Parameters:

property - the property

Returns:

the random field to fill this property; can be null

addRandomField

public void addRandomField(String property,
                           RandomField randomField)

Adds a RandomField to fill some property.

Parameters:

property - the property

randomField - the random field to fill this property; can be null

removeRandomField

public void removeRandomField(String property)

Removes a RandomField.

Parameters:

property - the property
