public class DDEIOPort extends TypedIOPort
DDEIOPorts are not necessary to facilitate communication between actors executing in a DDE model; standard TypedIOPorts are sufficient for most communication. DDEIOPorts become useful when the time stamp to be associated with an outgoing token is greater than the current time of the sending actor.
The designers of models that incorporate DDEIOPorts should be careful to make sure that output time stamp ordering information is correct. Since the output time stamp of a token being sent through a DDEIOPort can be greater then the sending actor's current time, it is possible on a subsequent token production to create an outgoing token with a time stamp that is greater than the current time but less then the previously produced time stamp. In such cases, an IllegalArgumentException will be thrown.

DDEIOPort()
Construct a DDEIOPort with no container and an empty
string as a name.
|
DDEIOPort(ComponentEntity container,
java.lang.String name)
Construct a DDEIOPort with a containing actor and the
specified name that is neither an input nor an output.
|
DDEIOPort(ComponentEntity container,
java.lang.String name,
boolean isInput,
boolean isOutput)
Construct a DDEIOPort with a container and the specified
name that is either an input, an output, or both, depending
on the third and fourth arguments.
