---------------------------------
Summary: Support value types (simple ones at least) as a
first-class citizen
Key: ISIS-1695
URL: https://issues.apache.org/jira/browse/ISIS-1695
Project: Isis
Issue Type: New Feature
Reporter: Dan Haywood
Priority: Minor
Fix For: 2.4.0
I would like to reintroduce value types as a first-class citizen, but without
requiring the developer to have to write lots of code to teach DataNucleus,
Wicket and the RO viewer about these.
I don't have a general solution in mind on how to do this.
However, for very simple value types that are just a type-safe wrapper around a
single field (eg Password, or Money, or Temperature, or Email say), then
perhaps there might be a way to support this, eg :
public class Temperature implements
org.apache.isis.valuetypes.Value<BigDecimal> { ... }
or
@Value(underlying=BigDecimal.class)
public class Temperature { ... }
