Package nl.jqno.equalsverifier.internal.valueproviders

Class UserPrefabValueProvider

java.lang.Object

nl.jqno.equalsverifier.internal.valueproviders.UserPrefabValueProvider

All Implemented Interfaces:

ValueProvider

public class UserPrefabValueProvider
extends Object
implements ValueProvider

Provider of prefabricated instances of classes that have been provided by the user. Note that this only works for non-generic classes, because this ValueProvider can't determine the generic types or get values for them. For that, we either need withPrefabValuesForField, or the complicated recursion mechanism that is currently provided by VintageValueProvider.
