[windup-dev] RuleProviders' / rules metadata

[Ondrej Zizka]

Hi,

it seems that the metadata is a bit scattered around the place.

A) Some metadata are at rules themselves, e.g. as returned by 
getExecuteAfter().

B) Some are sunken into the dark depth of ~.rewrite.Context, like

         rewriteCtx.put(RuleMetadata.CATEGORY, DEFAULT_CATEGORY);

However when I try to retrieve this,

         Object cat = event.getRewriteContext().get(RuleMetadata.CATEGORY);

I get null.
So I debugged and found the data stored in a weird data structure,

context.map[WindupRuleMetadata].providersToRules[?RuleProvider][?].contextMap

So I was trying to get it out,

         WindupRuleMetadata wrm = (WindupRuleMetadata) 
event.getRewriteContext().get(WindupRuleMetadata.class);
Assert.assertNotNull("event.getRewriteContext()[WindupRuleMetadata.class] is 
not null", wrm);
         for(WindupRuleProvider provider : wrm.getProviders())
         {
if(provider.getClass().equals(TestMetadataAnnotationExecRuleProvider.class))
                 continue;
             provider.get
         }


But here I got lost as there seems to be no API for providersToRules.

1) How can I get to the metadata?

2) I suggest to review where and how the metadata are stored and unify 
it a bit.

Thanks,
Ondra


PS: I admit that I didn't look much around for some working usages of 
metadata as I am going to sleep, but CATEGORY seems not to be used anywhere.
