Detailed Description

IUIDData is a data interface that holds onto a UIDRef (a <database, UID> pair) that can be used to uniquely describe a persistent object.

Member Function Documentation

UID IUIDData::Get ( void  ) const

inline

standard signature (Get()) method

virtual IDataBase* IUIDData::GetItemDataBase ( ) const

pure virtual

Get the database of the object

Returns

IDataBase* the database the object belongs to

virtual UID IUIDData::GetItemUID ( ) const

pure virtual

Get the UID of the object

virtual const UIDRef& IUIDData::GetRef ( ) const

pure virtual

Get the UIDRef of the object

virtual void IUIDData::Set ( const IPMUnknown *  item )

pure virtual

Set the value of the object. The pointer is for use inside the Set function only; the IPMUnknown* will be converted to a <database, UID> pair and held in that form, so that the object is not referenced.

Parameters

item	the new object

virtual void IUIDData::Set ( IDataBase *  db, UID  id  )

pure virtual

Set the value of the object.

Parameters

db	the database the object is in
UID	the object within the database

virtual void IUIDData::Set ( const UIDRef &  ref )

pure virtual

Set the value of the object.

Parameters

ref	the <database, UID> pair that describes the object
