CloneInto

Inside Macintosh: OpenDoc Class Reference /: Part 1 - Classes and Methods / ODStorageUnit

CloneInto
The CloneInto method copies all properties and values of this storage unit to the specified destination storage unit.
void CloneInto (in ODDraftKey key, 
                in ODStorageUnit destStorageUnit, 
                in ODID scopeID);
key
The draft key identifying this cloning operation.
destStorageUnit
A reference to the destination storage unit to which the data is to be copied.
scopeID
The ID of the frame that defines the scope of this cloning operation.

DISCUSSION
This method is not called by parts. Your part should call its draft's Clone or WeakClone method instead of this method.
If this storage unit has persistent references to other objects, the scopeID parameter determines which of the referenced objects are within the scope of this cloning operation. Typically, the scopeID parameter is the ID of a frame, and only those objects embedded in that frame are within scope. In the rare case in which the scopeID parameter is kODIDAll, all referenced objects are within scope.
This method copies this storage unit's data into the specified destination storage unit. If this storage unit has persistent references to other objects, this method clones any persistently referenced objects that are within the scope of this cloning operation. Objects referenced by strong persistent references are strongly cloned by recursive calls to the Clone method; objects referenced by weak persistent references are weakly cloned by calls to the WeakClone method.

EXCEPTIONS

kODErrInvalidDraftKey
The specified draft key is not the draft key for the current cloning transaction.
kODErrZeroRefCount
This storage unit has a reference count of 0.
