Class CustomType<T>

java.lang.Object
org.javers.core.metamodel.type.JaversType
org.javers.core.metamodel.type.CustomType<T>
Type Parameters:
T - Custom Type
All Implemented Interfaces:
CustomComparableType
public class CustomType<T> extends JaversType implements CustomComparableType
Custom Types are not easy to manage, use it as a last resort,
only for corner cases like comparing custom Collection types.

JaVers treats a Custom Type as a black box and doesn't take any assumptions about its content or behaviour. It's a "not modeled" type, somehow similar to unbounded wildcard <?>.

Objects of Custom Type are compared by a CustomPropertyComparator. Registering this comparator is the only way to map a Custom Type.

Custom Types are serialized to JSON using Gson defaults.
