XSClassCallbackCopy

Class copy callback

typedef XSMutableObjectRef ( *XSClassCallbackCopy )( XSObjectRef source, XSMutableObjectRef destination );

Discussion

The 'destination' parameter is an allocated object, without a constructor call. The return value is usually 'destination', but can be another object. If NULL is returned, 'destination' will be deallocated by the caller automatically.

Parameters

• source
  The object to copy
• destination
  The object beeing copied

Return value

The copied object
