Field Detail

GENERIC_TYPE_NOT_PARAMETRIZED

public static final java.lang.String GENERIC_TYPE_NOT_PARAMETRIZED

JaVers needs to know actual Class of elements stored in your Collections and Maps.
Wildcards (e.g. Set<?>), unbounded type parameters (e.g. Set<T>)
or missing parameters (e.g. Set) are defaulted to Object.class.

For Collections of Values it's a reasonable guess
but for Collections of Entities or ValueObjects you should use fully parametrized types (e.g. Set<Person>).
