Deserialize the object, according to its flags. This would have private
visibility, but is also used by LocalMemcacheService for the increment
operation.
if the object can't be re-instantiated due
to being an unlocatable type
makePbKey(Object key)
publicstaticbyte[]makePbKey(Objectkey)
Converts the user's key Object into a byte[] for the MemcacheGetRequest.
Because the underlying service has a length limit, we actually use the
SHA1 hash of the serialized object as its key if it's not a basic type.
For the basic types (that is, String, Boolean, and the
fixed-point numbers), we use a human-readable representation.
