How can I get a list of effective policySets for a given operation?
Hi,
If I have the (component, service/reference, binding, operation) model
instances handy, how can I get a list of effective policySets for the
operation? Are we consolidating the declarations at different levels to the
binding?
We can use the following example (I intentionally omit the @requires).
<component name="MyComponent" policySets="ns1:PS1">
<service name="MyService" policySets="ns1:PS2">
<operation name="op1" policySets="ns1:PS3">
<binding.xyz policySets="ns1:PS4 ns2:PS5">
<operation name="op1" policySets="ns1:PS6">
</binding.xyz>
</service>
</component>
Thanks,
Raymond

Hi Raymond,
I found a few holes that had crept into this part with the recent
'applicablePolicySets' related work. Am fixing them and should be done
anytime. Will not hold you back from your work for long. Thanks

Re: How can I get a list of effective policySets for a given operation?

What about an operation that is not explicitly customized by the <operation>
element? For example, if I have this:
<component ... policySets="ns1:PS1">
<service ... policySets="ns1:PS2">
<binding.xyz ... policuSets="ns1:PS3"/>
</service>
</component>
Can I do the the following?
OperationsConfigurator ops = (OperationsConfigurator) binding;
List<ConfiguredOperation> cops= ops.getConfiguredOperations);
If op1 is an operation on the service interface, is op1 on the cops list? If
yes, do I get ns1:PS1, ns2:PS2 and ns1:PS3 for op1?
Should I use PolicyAttachPoint.getPolicySets() or getApplicablePolicySets()
to get the list of effective policy sets?
Thanks,
Raymond

Hi Raymond,
SCA Artifacts that can have operations configured on them implement the
'OperationsConfigurator' interface. This interface has a method that will
return a list of 'ConfiguredOperation' and each element in this list
represents an operation that has been configured for policies. The
'ConfiguredOperation' extends a PolicySetAttachPoint and hence you should be
able to get the list of policysets from this.
Yes, we do aggregate the intents and policysets upto the operation level.
Let me go and add a test for the scenario you have mentioned here, in the
itest-policy. I will post back once that is done
Thanks
