Delete object from collection versus delete from JPQL

I'm a newbie, so this is a pretty fundamental question. I'm not sure if there is a bi-directional relationship between the objects in memory and ObjectDB.  I know I can modify the objects and use persist() to write them to the database.  But does running a JPQL update or delete alter the in-memory objects? There are cases where the JPQL syntax is more expressive than operating on a collection, but I'm not sure if that will alter my program state.  Will it? Thanks, Lee  #1 2014-03-24 22:25 I'm a newbie, so this is a pretty fundamental question. I'm not sure if there is a bi-directional ...
