示例1: CreateDelta

 /**
  * Build a new set (in memory) made of objects of the given set which are NOT present in the current set
  * 
  * Limitations:
  * The objects inside the set must be written in the database since the comparison is based on their identifiers
  * Sets with several objects per row are NOT supported
  * 
  * @param DBObjectSet $oObjectSet
  * @throws CoreException
  * 
  * @return DBObjectSet The "delta" set.
