ObjChangeMask Class Reference

Defines what messages if any are passed to parent objects. The starting message is not defined here as this is used to allow nodes to actually set the mask. All flags are initialised to FALSE and should be set by nodes to TRUE when they want to receive a message. If any parent node requires a message then all will get the message. Note the mask is verified and corrected so that messages will be sent correctly in sequence. More...

 ObjChangeMask ()
 constructor for ObjChangeMask. This sets the various maskable changes to false, ie they will not be sent during and interactive change.
void CorrectMask ()
 Checks the ObjChangeMask settings and corrects them where necessary. It thus ensures object change messages are not called out of sequence or or missed out when necessary.
void ClaimAll ()
 A quick way of setting all the mask bits to true, for a particular ObjChangeMask. This starts forcing all ObjChange messages for a particular op to be sent.
