示例1: removeAllObjects
/**
* Unlinks any ca_objects rows related to the currently loaded ca_object_lots record. Note that this does *not*
* delete the related objects. It only removes their link to this lot. Note that on error, the database maybe left in
* an inconsistent state where some objects are still linked to the lot. If you want to prevent this then wrap your
* call to removeAllObjects in a transaction and rollback the transaction on error.
*
* @return boolean Returns true on success, false if there were errors.
