| Operations |
|---|
| void | - add(MessagePort port)
- The add() method must add the
MessagePort given by the argument to the PortCollection object's list of ports, unless the MessagePort is
already in the list of ports, in which case the
method does nothing. (Calling this method with a port already in the list does not move the port
to the end of the list.)
|
| void | - clear()
- The clear() method must remove all
MessagePort objects from the PortCollection object's list of ports, returning it to the initial empty state. If the list of ports is already empty, the method
does nothing.
|
| void | - iterate(PortCollectionCallback callback)
- The iterate() method must invoke its
PortCollectionCallback argument once for each MessagePort object in the
object's list of ports, in the order defined
above, with each invocation being passed the corresponding MessagePort object as the
callback's sole argument.
|
| void | - remove(MessagePort port)
- The remove() method must remove the
MessagePort given by the argument from the PortCollection object's list of ports, unless the MessagePort is
not in the list of ports, in which case the
method does nothing.
