    Switches the switch off (if on), uses locking

  23. def switchOff(action: => Unit): Boolean

    Executes the provided action if the lock is on under a lock, so be _very_ careful with longrunning/blocking operations in it Only executes the action if the switch is on, and switches it off immediately after obtaining the lock Will switch it back on if the provided action throws an exception

  24. def switchOn: Boolean

    Switches the switch on (if off), uses locking

  25. def switchOn(action: => Unit): Boolean
