Sets the object as not being dirty for all dirty flags.

setIsRepresentable(self, isRepresentable: bool) → None

Sets the object to be saved to session files or not.

Parameters:pIsToBeSaved (bool) – true to cause the object to be saved to session files, false otherwise

Note

The private title can later be used to find a reference to that object, given that it’s still alive.

The arguments oldContextID and newContextID are used as strings instead of plugin instances to support the situation where the old or new context is not existing (for example, to perform a copy of the objects).

Parameters:
  • oldContextID (str) – old context ID
  • newContextID (str) – new context ID
