[MOBY-l] Determine if Central's cache is filled

[Martin Senger]

Hi,

In jMoby, how can I determine if the cache in my
> CentralDigestCachedImpl is filled with e.g. serviceTypes? I can get
> the age of the registry but that is not what I need.


There are some protected methods that could be made more public if needed.
At the moment, however, you can use method

public Properties getCacheInfo (String id);

where as 'id' you can specify the cache you wish to investigate. For
example, for service types cache, you use:

getCacheInfo (CentralDigestCachedImpl.CACHE_PART_SERVICETYPES);

You get back properties - and some properties are missing if the cache is
empty. You can use as an example class CacheRegistryClient.java. This class
can be invoked by run-cache-client:

If a cache exists, it looks like this:

-cachedir myCache/
Cache for Service Types
        Biomoby registry

When a removed the service type cache and run the same script again, I got
only:

senger at sherekhan:~/moby-live/Java$ build/run/run-cache-client -info-t
-cachedir myCache/
Cache for Service Types
