Dan Haywood updated ISIS-454:
-----------------------------
Component/s: Core
Affects Version/s: core-1.2.0
There is already the DisabledObjectViaDisabledMethodFacetFactory which does
something very similar...
String disable(Interaction.Type.Xxx) { ... }
The only thing this doesn't support, I think, is the precedence rules.
> New mechanism to disable members "globally". However, any disablement rules
> applied on the member should overrule the policy defined on the type.

> If done using a method, this would be something like:
> public String disable(String memberName, MemberType memberType) {
> if(memberName.equals("notes")) { return null; }
> if(memberType == MemberType.PROPERTY) {
> WithStatus ws = (WithStatus)domainObject;
> return ws.isLocked()? "cannot modify because locked": null;
> }
> return null;
> }
> If done using an annotation, this would be something like:
> @Disabled(policy=StateIsLockedPolicy.class)
> public abstract class MyDomainObject<T extends EstatioDomainObject<T>, S
> extends Lockable> extends MyDomainObject<T> implements WithStatus<T,S> {
> public static StateIsLockedPolicy implements DisabledPolicy {
> public String disable(Object domainObject, String memberName,
> MemberType memberType) {
> if(memberName.equals("notes")) { return null; }
> if(memberType == MemberType.PROPERTY) {
> WithStatus ws = (WithStatus)domainObject;
> return ws.isLocked()? "cannot modify because locked": null;
