Puzzled at MemObject and StoreEntry. :-(

Hi, pals!

After reading source codes for several days, I have such
opinions on MemObject and StoreEntry, please check whether
my opinions are correct.

1. The object being accessed has its member memObject, and
the other StoreEntry's memObject is NULL.

Am I correct at this point?

2. Even though the object being accessed is on disk and not
in memory, the StoreEntry also has memObject member ( the memObject member of it is not NULL). So whether the memObject is NUll or not NULL has nothing to do with whether the object (StoreEntry pointing to) is on disk or in memory.

Am I correct at this point?

Best regards,
George Ma
