/** This implementation of KeyRing provides a cached view of PublicKeyRing
* objects based on database queries exclusively.
*
* This class should be used where only few points of data but no actual
* cryptographic operations are required about a PublicKeyRing which is already
* in the database. This happens commonly in UI code, where parsing of a PGP
* key for examination would be a very expensive operation.
*
* Each getter method is implemented using a more or less expensive database
* query, while object construction is (almost) free. A common pattern is
* mProviderHelper.getCachedKeyRing(uri).getterMethod()
*
* TODO Ensure that the values returned here always match the ones returned by
* the parsed KeyRing!
