Assembly Question - Property interface hierarchy
Hi,
In the Assembly module can I change the Property interface hierarchy as
follows:
- Have ComponentProperty extend from AbstractProperty instead of Property.
- Move the 'defaultValue' accessors into 'Property' from AsbtractProperty
- Introduce accessors for 'value' in ComponentProperty.
Right now the value for a ComponentProperty gets read into the
'defaultValue' field and I just want this to move into 'value' field.
Opinions on this change proposal? Thanks.

Ok... this makes sense to me... I'll go ahead and make this change. Thanks

From the SCA assembly spec, it looks like constrainingType/property can
specify a value as well, so AbstractProperty needs a way to specify a
value. How about just renaming the defaultValue field to value? If we
did that then the structure would be similar to References and Services.
A Reference can have some characteristics (like targets or bindings)
configured in a ComponentType, then reconfigured on a
ComponentReference. Similar for Property, the Property could have its
value configured in a ComponentType, then reconfigured on a
ComponentProperty.
