These interfaces are implemented on local DCOM value objects (ISynchronizeis found on COM proxies, DISynchronize is found
on Automation proxies). If the interface is available, it means that this is a local DCOM value object, not a regular object
or a primary DCOM value object.
20.6.2.1 Mode Property
The property Mode is used to control when synchronization is done. A value of kNeverSync means that the local and the primary
value objects are never synchronized.
A value of kSyncOnSend means that, if the local value object has been changed, the primary value object will be synchronized
with the local value object when the local value object is sent to another client/server, which cannot be reliably determined
to support the required DCOM value object. Implementations can choose to synchronize using either batch synchronization through
a call to IValueObject, or through calls for each changed member through the regular remote interface.
A value of kSyncOnChange means that, as a member is changed, the update of the member should be propagated to the primary
value object as a regular remote call.
20.6.2.2 SyncNow Method
The SyncNow method can be called by application code to force the changes to the local value object to be propagated to the
primary value object. Implementations can choose to synchronize using either batch synchronization through a call to IValueObject,
or through calls for each changed member through the regular remote interface.
20.6.2.3 ReCopy Method
The ReCopy method can be called by application code to retrieve the current value of the primary value object and update the
local value object.
