Pause

This state is the only exception, i.e. G4 kernel will not set this state from any other states. User can explicitly set G4 application to this state. The method the user can set this state is

G4StateManager::getStateManager()->pause();
The G4 state will toggle from the previous state to Pause and then go back to the previous state automatically. The G4VStateDependent::notify() method will be invoked with the state change to Pause state. Be careful that Pause->previousState will not be notified.
