- Method Detail
  - init
```
public void init(boolean b,
                 int d)
```
    Re-init event content. This method can be used to rewrite an existing event with new data (much cheaper than making a new object).
    
    Parameters:
    
    b - A boolean flag; when false it means that a behaviour passed from Ready to Blocked state. When true it means that a behaviour passed from Blocked to Ready (this flag is the truth value of the predicate 'The behaviour has now become runnable'.
    
    d - A notification direction: when direction is NOTIFY_UP, the event travels upwards the behaviour containment hierarchy; when it is NOTIFY_DOWN, the event travels downwards.
  - getSource
```
public Behaviour getSource()
```
    Read event source.
    
    Returns:
    
    The Behaviour object which generated this event.
  - isRunnable
```
public boolean isRunnable()
```
    Check whether the event is runnable.
    
    Returns:
    
    true when the behaviour generating this event has become Ready, false when it has become Blocked.
  - isUpwards
```
public boolean isUpwards()
```
    Check which direction this event is travelling.
    
    Returns:
    
    true when the event is a notification going from a child behaviour to its parent; false otherwise.
