public class SubscriptionAggregatorPort extends SubscriberPort
This is a generalization of the SubscriberPort (the base class) where the channel name
is interpreted as a regular expression. Data produced by all
publishers that publish on a channel name that matches the regular
expression are aggregated using the operation given by the operation parameter.
Note that the channel
parameter of the superclass is now a regular expression in this class.
One thing to watch out for is using . instead of \..
For example, channel.foo does not mean the same thing as
channel\.foo. The latter requires a dot between channel and
foo, where the former does not.
Note that although this is a multiport, calls to get() should only reference channel 0. An exception will be thrown otherwise. The result of the get will be the aggregate of what is received on all the input channels.

| Modifier and Type | Method and Description |
|---|---|
protected int |
_getInsideWidth(IORelation except)
Override the base class to always return 1.
|
protected void |
_updateLinks()
Update the connection to the publishers, if there are any.
|
void |
attributeChanged(Attribute attribute)
If a publish and subscribe channel is set, then set up the connections.
|
Token |
get(int channelIndex)
Get a token from the specified channel.
|
Token[] |
get(int channelIndex,
int vectorLength)
Get an array of tokens from the specified channel.
|
int |
getWidthInside()
Return the inside width of this port, which in this class is
always 1.
|
boolean |
hasToken(int channelIndex)
Return true if any input channel has a token.
|
boolean |
hasToken(int channelIndex,
int vectorLength)
Return true if every input channel that has tokens has enough tokens.
|
void |
preinitialize()
Check that the port is not in the top level, then
call preinitialize() in the super class.
