Method Detail

getRecordByUserObject

ORecord getRecordByUserObject(Object iUserObject,
                              boolean iCreateIfNotAvailable)

Returns the record associated to a user object. If iCreateIfNotAvailable is true, then a new record instance will be created transparently.

Parameters:

iUserObject - User object

iCreateIfNotAvailable - Create the record if not available

Returns:

The record associated

getUserObjectByRecord

Object getUserObjectByRecord(OIdentifiable iRecord,
                             String iFetchPlan)

Returns the user object associated to a record. If the record is not loaded yet, iFetchPlan will be used as fetch plan.

Parameters:

iRecord - Record

iFetchPlan - If the record is not loaded yet, use this as fetch plan

Returns:

The user object associated

existsUserObjectByRID

boolean existsUserObjectByRID(ORID iRID)

Tells if e user object exists for a certain RecordId.

registerUserObject

void registerUserObject(Object iUserObject,
                        ORecord iRecord)

Registers the association between a user object and a record.

Parameters:

iUserObject - User object

iRecord - record

registerUserObjectAfterLinkSave

void registerUserObjectAfterLinkSave(ORecord iRecord)

Registers the saved linked record. Needed only to make the old object database implementation work

Parameters:

iRecord - record
