Interface Space
- All Superinterfaces:
- Collection, DynamicCollection, Listener, Ticklish
- All Known Subinterfaces:
- QTDisplaySpace
- All Known Implementing Classes:
- SimpleSpace
- public interface Space
- extends Listener, DynamicCollection, Ticklish
A Space is a dynamic collection of members. A Space also has
a Timer and a collection of Controllers. The Timer
provides the parent TimeBase for all members and controllers
within the Space that are themselves Spaces or objects that
have a TimeBase. The getSource method returns the source
object which the Space has been addedTo (ie. the Space is also
a Listener).
The tickleList is the list of TicklishControllers that have been
added to ths Space and will be tickled by the Space when the Space
itself is tickled by its Timer.
A default implementation of the Space interface is provided in
the SimpleSpace class - refer to the documentation for details
of that implementation.

Method Summary |
void |
addController(Controller c)
This method is used by the application to add a Controller to
the Space. |
java.util.Enumeration |
controllers()
Returns an Enumeration of all Controllers that are currently
attached to the Space. |
java.lang.Object |
getSource()
This object is the source for all of the members and controllers of the Space that
implement the Listener interface. |
Timer |
getTimer()
Returns the Timer of the Space. |
void |
removeController(Controller c)
Removes a controller that was previously added to the Space. |
java.util.Enumeration |
tickleList()
Returns an Enumeration of all of the Controllers that implement the Ticklish interface
(TicklishControllers) that have been added to the Space. |
addController
public void addController(Controller c)
throws QTException
- This method is used by the application to add a Controller to
the Space. A Controller will control members of a Space.
- Parameters:
c
- the Controller to add to the Space.
removeController
public void removeController(Controller c)
throws QTException
- Removes a controller that was previously added to the Space.
- Parameters:
c
- the Controller to remove from the Space.
controllers
public java.util.Enumeration controllers()
- Returns an Enumeration of all Controllers that are currently
attached to the Space.
- Returns:
- an Enumeration
tickleList
public java.util.Enumeration tickleList()
- Returns an Enumeration of all of the Controllers that implement the Ticklish interface
(TicklishControllers) that have been added to the Space. These controllers are tickled
each time the Space itself is tickled by its Timer.
- Returns:
- an Enumeration of Ticklish objects
getTimer
public Timer getTimer()
- Returns the Timer of the Space. This Timer provids a TimeBase for the Space and
if active will tickle and send timeChanged calls to the TicklishControllers that
are attached to the Space.
- Returns:
- a Timer
getSource
public java.lang.Object getSource()
- This object is the source for all of the members and controllers of the Space that
implement the Listener interface. All such members and controllers will have the same
source as the parent space when it is addedTo a Listener source. If the parent Space
has not been added to a Listener source this returns null.
- Returns:
- the Listener source object
