Undo and redo

Most functions of the SAMSON SDK that have an action on the data graph's state are undoable. When it is the case, the function documentation has a special mention: This function is undoable

Example

SBCamera* camera = SAMSON::getActiveCamera();   // get the active camera
 
SAMSON::beginHolding("Change camera name");     // turn the Undo system on
camera->setName("New camera name");             // change the camera name
SAMSON::endHolding();                           // turn the Undo system off
 
SAMSON::undo();                                 // undo the name change

See the User guide: History for the user's representation of the undo and redo mechanism.
