abstract class DeepaMehtaObjectImpl
extends Object
implements DeepaMehtaObject

A DeepaMehta object model that is attached to the DB. Method name conventions and semantics: - getXX() Reads from memory (model). - setXX(arg) Writes to memory (model) and DB. Elementary operation. - updateXX(arg) Compares arg with current value (model) and calls setXX() method(s) if required. Can be called with arg=null which indicates no update is requested. Typically returns nothing. - fetchXX() Fetches value from DB. ### FIXDOC - storeXX() Stores current value (model) to DB. ### FIXDOC
