org.mockito.internal.util.reflection.FieldInitializer

public class FieldInitializer
extends java.lang.Object

Initialize a field with type instance if a default constructor can be found.

If the given field is already initialized, then the actual instance is returned. This initializer doesn't work with inner classes, local classes, interfaces or abstract types.
