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

getType

public final DeepaMehtaType getType()

Description copied from interface: DeepaMehtaObject

Returns the type of this object.

No access control is performed as Implicit READ permission applies: if a user has READ access to an object she has READ access to its type as well.

Note: if the user would have no READ access to this object the DeepaMehta Core would not instantiate it in the first place, but throw an AccessControlException.

Specified by:
