Implementation of the Observer Pattern.
Parameters
- $observer : \SplObserver
ensure()
array &$ensuredObjectsList = array ( )
Ensures the value.
Parameters
- $forceObservation : bool
- $ensuredObjectsList : array
A list of all ensured indirect objects to prevent recursion
See
getValue()
Get the value object.
notify()
Notifies all attached observers.
Implementation of the Observer Pattern.
Has to be called by any method that changes a value.
setKey()
setValue()
toPdfString()
